🔗 What Is a URL Shortener? A URL shortener takes a long, unwieldy link and compresses it into a much shorter version — one that’s easier to share and remember. Example: Long: https://example.com/products/category/item?utm_source=email&utm_campaign=sale Short: https://cthshort.xyz/xyz123 Clicking the shortened link redirects the user seamlessly to the full URL. You input your long link. The system generates a unique alias (or lets you set a custom one if you're a premium user). This alias is stored with the original link in a local database. When someone clicks the shortened link, they’re instantly redirected to the original. Some platforms also support extras like analytics, expiration times, and branded URLs — and Cipher Tools Hub delivers these without compromising privacy. ✅ Custom A…  ( 4 min )

England had already faced a penalty shootout in the quarterfinal against Sweden. two saves by Hannah Hampton. That match gave the team more than a win — it gave them trust in their goalkeeper. “If we reach penalties, we know we can win.” And during the game, England played as if that plan was clear from the start.

Look, I've been in those sprint planning meetings. You know the ones—where someone spends 20 minutes explaining why updating a button color is "definitely an 8-point story" while the actual CSS change takes exactly 47 seconds. After years of watching teams drown in ceremonies, standups, and retrospectives that somehow never make anything retrospectively better, I'm convinced we're doing this wrong. Sprint planning shouldn't feel like performance art. It should help us ship code faster and with less stress. Most agile consultants have never pushed code to production at 2 AM on a Friday. They've never had a "simple bug fix" turn into a three-day archaeology expedition through code written by someone who left the company in 2019.

In our fast-moving digital world, data is always in motion. Every time someone opens a mobile app, receives a GPS notification, completes an online purchase, or interacts with a smart device, fresh data is generated. These small actions add up, creating a constant stream of valuable information. For businesses that want to stay ahead, reacting to this ingested data in real time is no longer optional—it’s essential. Traditional methods like batch processing involve storing data, waiting for accumulation, and then analyzing it in large chunks. While effective in the past, this approach delays insights and decision-making.

In the ever-evolving world of digital marketing, one tactic stands out for its ability to amplify reach, boost brand credibility, and drive meaningful engagement: partnered webinars. Also known as co-branded webinars, this approach involves teaming up with complementary brands, micro-influencers, or niche content creators to deliver joint webinars that provide value to shared audiences. Why Partnered Webinars Work Choosing the Right Partners Make sure your partner shares similar brand values, audience interests, and expectations for the collaboration. Define Mutual Goals Start by aligning on what success looks like - whether it's lead generation, brand awareness, sales enablement, or community building. Create Compelling Content Build your topic around a real pain point or trending subject that matters to both audiences. Make it informative, not salesy. Divide Responsibilities Assign roles - who will present, who will moderate, who will handle promotion, and who manages follow-up. Clear ownership prevents confusion. Promote Across Channels Leverage both partners' email lists, social channels, LinkedIn communities, and paid promotions if the budget allows. Use co-branded graphics for consistency. Engage During and After the Webinar Encourage Q&A, polls, and live chat to increase participation. After the event, share the recording and follow up with attendees using tailored nurture campaigns. Metrics That Matter To assess your webinar's success, track the following KPIs: Number of registrants and actual attendees Engagement rate during the webinar Lead conversion rate post-event Email list growth Social media mentions or shares These insights will help both partners understand ROI and refine future collaborations.  ( 4 min )

❌ The Wrong Belief: When people first hear about Time Complexity, they often think: But this is not correct Student A writes this simple code in JavaScript: for (let i = 0; i < 1000000; i++) { console.log(i); } 💻 16GB RAM ⚡ SSD (Solid State Drive) 🚀 Fast multi-core CPU His program runs and finishes in just 1 second. Student B writes exactly the same code: for (let i = 0; i < 1000000; i++) { console.log(i); } 🖥️ 4GB RAM 🐢 Slower CPU 🧓 Mechanical hard drive Her program takes around 5 seconds to finish. No! Absolutely not. Both students wrote the exact same code using the same algorithm — a simple for loop that runs 1 million times. So why the performance difference? Factor Student A (Faster) Student B (Slower) RAM 16GB 4GB CPU Speed Fast, modern processor Older, slower processor Disk Type SSD (fast) HDD (slower) System Performance High Low For example, the same algorithm written in C++ may run faster than in Python because: C++ is a compiled language — the code is converted directly into machine code before execution, which makes it run very fast. Python is an interpreted language — the code is executed line-by-line by an interpreter at runtime, which usually makes it slower. Language Type Performance Impact C, C++, Rust Compiled Generally faster execution times due to direct machine code output Python, JavaScript, Ruby Interpreted Slower because code runs through an interpreter or virtual machine ✅ So What Is Time Complexity Then?  ( 4 min )

Let’s kill the myth right here: there is no such thing as a "quick design audit." But teams keep saying it anyway — usually when conversion rates tank, user complaints pile up, or someone on Slack writes, “Something about this just feels... off.” That’s when the magic phrase gets dropped, always with a hint of optimism and a deadline like "can you do it by Thursday?" Here’s what they want: a neat bullet list of UI tweaks. Some line spacing fixes. Maybe a smart-sounding insight they can quote in a stakeholder meeting. Here’s what they actually need: a wake-up call. The phrase “design audit” sounds polite — like someone will check your alignment and hand you a report. But when done right, it’s a teardown.

Our policy is to support browsers released within the last two years. Previously, we used Browserslist to transpile our code and automatically add polyfills.

Fortunately, there's a package that does exactly that: browserslist-useragent-regexp. It generates a regular expression based on your Browserslist config, which you can run against navigator.userAgent.

For years, developers have relied on centralized cloud giants like AWS, Google Cloud, or Azure to deploy applications. They work, but they also come with high costs, vendor lock-in, and limited transparency. When it comes to AI-driven decentralized applications (dApps), the problem becomes even worse: AI workloads are expensive and require massive compute power. Hosting AI models on centralized clouds means sacrificing transparency. Most blockchains can’t handle complex AI tasks due to scalability issues. This is where platforms like haveto.com come in, allowing developers to deploy AI dApps directly on-chain without touching centralized infrastructure. haveto.com is redefining how developers build AI-powered applications.

Why learning product every day while building gives you an unfair advantage Building a startup without learning product is like driving with foggy windows. You’re moving, but you’re not really seeing where you're going. A lot of solo founders and indie hackers fall into the same trap: they ship stuff and hope for the best. They think speed equals progress. But if you're shipping the wrong thing, speed just takes you further off course. Meanwhile, the founders who spend just 10 minutes a day improving their product skills make sharper calls and avoid the dumb mistakes. That’s what gives them an edge. This isn’t about theory or frameworks. It’s about learning just enough, every day, to improve how you build and what you decide. Small, consistent effort beats big learning sprints. If you sp…  ( 5 min )

AI is everywhere right now from flashy GPT-5 demos to enterprise copilots that promise to do your job for you. But if you're like me, you're more interested in what you can actually use today as a developer. Forget the hype. I’ve spent the last few months exploring a bunch of open-source AI tools that are already making my workflow faster, cleaner, and honestly more fun. These aren’t vague “AI productivity” platforms they’re focused, well-built tools designed for developers who build, test, debug, and ship things. If you’ve been curious about what open-source AI is capable of, or just want to cut down on repetitive work without relying on closed black boxes, this list is for you. Before jumping into the tools, here’s why I lean open source for most of my AI stack: Transparency: I can audit…  ( 8 min )

When building MCP servers, we often focus on the happy path: what happens when tools execute successfully. But what about when things go wrong? The quality of your error responses can make the difference between a frustrated user and an AI that recovers gracefully on its own. Before diving into error response strategies, it's crucial to understand the distinction between two types of errors in MCP: These are errors in the MCP communication itself: Connection closed or request timeout Tool not found Malformed requests or protocol violations Internal server errors These errors trigger standard JSON-RPC error responses and typically indicate something is fundamentally broken with the request or the server. { "jsonrpc": "2.0", "id": 1, "error": { "code": -32001, "message": "Reque…  ( 5 min )

Watching live football online has become more accessible than ever, thanks to a variety of free streaming platforms. As a web developer interested in performance optimization and streaming tech, I decided to analyze how these platforms perform under the hood. One interesting platform I came across is futbol libre, which provides free access to live football matches from various global leagues like La Liga, Copa Libertadores, and more. Using Chrome DevTools and Lighthouse, I ran performance audits on futbol libre to understand: Time to First Frame Buffering behavior on slower networks JavaScript bundle sizes Third-party script load times Mobile responsiveness Initial load time was relatively fast (~1.2s on 4G). Minimal layout shifts, even with embedded video players. Ad scripts were present, but didn't significantly affect load performance. Responsive design worked well across devices. Google Chrome DevTools Lighthouse CLI WebPageTest (for cross-validation) uBlock Origin (to compare ad vs. no-ad performance) Platforms like futbol libre show that free sports streaming can be performant — but also come with challenges like maintaining stability, avoiding spammy ads, and ensuring compliance with local laws. If you're interested, I’ll publish a follow-up with automated Puppeteer scripts to run continuous audits on similar platforms. Let me know in the comments!  ( 3 min )

When I joined a fast-growing SaaS company three years ago, we were processing about 10,000 images per day with a simple Node.js service and basic JPG conversion. Fast forward to today: we handle over 50 million images monthly across 15 microservices, supporting 200+ engineers across multiple teams and time zones. The journey from startup-scale to enterprise-scale image processing taught me that technical optimization is only half the battle. The real challenges emerge around team coordination, operational complexity, cost management, and maintaining consistency across distributed development teams. Let me share the architectural decisions, organizational patterns, and hard-won lessons that enabled us to scale without sacrificing developer velocity or system reliability. // Our original "si…  ( 15 min )

Looking to move beyond simple LIKE queries in SQL? PostgreSQL offers native full text search, a powerful feature for matching and ranking text intelligently. It supports stemming, stop words, ranking, and multiple languages—all within your database. This guide walks you through how it works, how to implement it, and how to make it fast and accurate using tsvector, tsquery, and GIN indexes. Text → tsvector Query → tsquery Use @@ to match Add GIN index for speed Use ts_rank() to sort by relevance ALTER TABLE products ADD COLUMN tsv tsvector GENERATED ALWAYS AS ( to_tsvector('english', name || ' ' || description) ) STORED; CREATE INDEX tsv_idx ON products USING GIN(tsv); SELECT * FROM products WHERE tsv @@ to_tsquery('english', 'sneaker & casual'); Phrase queries: SELECT * FROM products WHERE tsv @@ phraseto_tsquery('english', 'everyday wear'); Rank by relevance: SELECT name, ts_rank(tsv, to_tsquery('english', 'wear')) AS score FROM products; setweight() to boost titles ts_headline() to highlight matches Combine tsvectors from multiple fields Can I search across multiple columns? Yes, combine them using || or setweight() into one tsvector. How do I match full phrases? Use phraseto_tsquery() for phrase-based searches. How do I rank results? Use ts_rank() and assign weights to important fields. Is it better than LIKE? Yes — FTS is more powerful, accurate, and performance-optimized. PostgreSQL Full Text Search is the easiest way to build a search engine directly in SQL. Fast, powerful, and production-ready.

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space I created The Hive Intranet, a clean, responsive internal platform designed for a remote-first social media agency. The goal was to build something functional, minimal, and tailored to real daily needs. I focused on layout clarity, fast access to tools, and smooth usability across screens. The interface uses a soft white and gray background with orange accents to highlight actions and data points. It’s structured into six main sections, each designed with purpose. Smart Hub A daily productivity area. It includes a simple task tracker (Quick Wins) and a learning widget that rotates new content. These help team members focus and stay up to date. KPI & Tools This section holds key stats like project completions, client count, and satisfaction rate. Right beside it, I added shortcut icons to tools like Google Docs, Asana, SEMrush, Buffer, and Claude. With this no need to switch tabs, just jump into your favorite work tools. Company News A simplified announcement area. It shows a featured story with an image and a list of updates. I stripped it down to reduce noise but keep everyone in the loop. Projects Showcase Navigation Demo The Hive Intranet Code Live URL This project was a good mix of design thinking and frontend structure. I went with a mobile-first approach and paid attention to small UX details, like making the tool icons easy to reach and ensuring grid behavior stays solid on small screens. I kept the CSS lean and used variables for easy theming. The HTML is semantic and accessible. I removed unused code before shipping, keeping everything clean for production. The sections were chosen based on how remote teams actually work—daily focus, fast tool access, visible progress, and lightweight communication. Every part plays a role in keeping the team in sync.  ( 4 min )

I still remember the first time I saw Power Automate Copilot, it was at the Power Platform Conference back in 2023, back then it had random compose and did a condition in a loop (a big no no for me). Call out, I don't use Copilot in Power Automate, so my experience is limited and my prompts are probably not the best (Though I do use GitHub Copilot and T3 Chat so have some experience in LLMs). Additionally I'm not testing the expression generator, just creating actions. So the plan is to look at updating a flow with prompted that cover: Loops (easy to get wrong and burn API calls) Error/Exception Handling Conditions (often unnecessary) And finally a prompt to complete an entire flow.

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space Intradash is a webapp dashboard with widgets that give you easy access to your data, but also lets you build your own spaces so you can organize things the way you want it (more on that later). Some main features include: A problem with compact UI sections, is that it can be hard to find data or tedious to navigate, that is why each dashboard widget has a button that can allow you to maximize that widget and be more focused and comfortable. In my experience working with others, I've noticed that sometimes, being organized is very difficult. Maybe there is an event, or there are different tasks that you realize daily or every certain amount of time, and it would be a lot easier if you could have predefined spaces with just exactly what you need without jumping from one place to another. That's why I added the “Bento Builder”, in simple words, these are customizable spaces with layouts similar to a bento, there, you can place different widgets and set the data you want. Live Preview: Intradash Preview Repo: Code Here As a person who have created templates in the past, I think this was an interesting experience, this was an area felt new for me and I didn't know there was a market for this until I saw what Axero is doing (at least, not like a whole area I think), so I'm looking forward to explore more in that area. I think, that by far, as a front-end developer, this has been one of the more complex interesting project I've worked.

Introduction While working on a side project, I thought, "Why not add a Google login feature?" "Google login? Shouldn't it be as simple as creating a button and calling a few APIs?" Little did I know how much of a learning journey this thought would become. From my first encounter with the term OAuth 2.0, I learned so much. The experiences of getting lost in the Google Cloud Console, almost committing environment variables to Git, and struggling to figure out why a popup wouldn't appear have now become a valuable learning process. "It was more complicated than I thought... but I figured it out one step at a time!"

Six years ago, I wrote my first blog post... and heard crickets. Nobody was reading my blog. I wanted some traffic there. Some attention. I was playing the SEO game with keywords and answer posts. I prayed to the SEO gods to send readers to my blog. Those days, I found out about dev.to, the new platform in town for coders. A better way to get readers? Create an account and repost there. So on July 23rd, 2019, I did it. I didn't know where it would take me. In six years, I've written 176 posts. Some of them are dev.to "originals." Others reposts. I wrote more posts, but I deleted the oldest in a moment of embarrassment. Yes, even I cringed at reading them. They were so bad. My posts have received +114K views and 1.6K reactions. And I have +25K followers. Mostly bots or inactive users I thin…  ( 4 min )

How I Built EduConnect – A Platform to Bridge the Gap Between Students and Faculty The Idea The concept for EduConnect was quite straightforward: I aimed to close the communication gap between faculty and students while helping students team up with the right partners for hackathons. A lot of students find it hard to reach out to faculty when they’re facing challenges, especially when they’re learning a new language or framework. Plus, they usually form hackathon teams based on who they know rather than skills, which can lead to subpar results. To tackle this issue, I started creating EduConnect – a web app that allows: Students to chat with their classmates and professors. Faculty to be filtered by their expertise (such as Python, Java, etc.). Students to connect with team m…  ( 4 min )

In the gold rush of AI, it’s easy to build a thin wrapper around an API, create a flashy demo, and call it a day. But building robust, scalable, and secure AI infrastructure—the kind you can bet your business on—is a different game entirely. It requires deliberate architectural choices and a deep understanding of production systems. At Context Space, we aren't just building features; we're engineering a foundation. Our vision is to provide a tool-first infrastructure that powers the next generation of complex AI agents. Here’s a look at the core technical advantages that make this vision possible. The Problem: The most glaring security hole in most AI agent setups is credential management. API keys, OAuth tokens, and other secrets are often dumped into .env files, checked into insecure dat…  ( 5 min )

Getting Started with Azure Container Apps and Dapr Azure Container Apps is a serverless container platform that enables you to deploy microservices without managing complex infrastructure. When combined with Dapr (Distributed Application Runtime), it unlocks powerful capabilities like service invocation, pub/sub messaging, state management, and more—ideal for building resilient, cloud-native apps. Azure CLI Dapr CLI A GitHub repo or container image (e.g., from Docker Hub) Azure Subscription Install the required extensions: az extension add --name containerapp --upgrade az provider register --namespace Microsoft.App az provider register --namespace Microsoft.OperationalInsights az group create --name dapr-app-rg --location westus az containerapp env create \ --name dapr-env \ --resource-group dapr-app-rg \ --location westus Deploy a sample app with Dapr sidecar: az containerapp create \ --name dapr-service \ --resource-group dapr-app-rg \ --environment dapr-env \ --image ghcr.io/dapr/samples/hello-k8s-node:latest \ --target-port 3000 \ --ingress external \ --enable-dapr \ --dapr-app-id nodeapp \ --dapr-app-port 3000 --enable-dapr deploys the Dapr sidecar --dapr-app-id is used for service invocation To invoke the service from another app or tool: curl http:/// \ -H "dapr-app-id: nodeapp" Attach a pub/sub component or state store by uploading a Dapr component YAML file to your Container App environment via the Azure Portal or Azure CLI. For example, use Azure Storage, Service Bus, or Redis as backends. By enabling Dapr in Azure Container Apps, you can focus on building scalable microservices without worrying about infrastructure. You get out-of-the-box service discovery, retries, pub/sub, and state—making your app more robust and cloud-native.  ( 3 min )

Okay, seriously, if you’re anything like me, your eyeballs were glued to every little bit of news coming out of San Diego Comic-Con this past weekend. And while there were a ton of huge reveals, one definitely stood out for fans of a certain highly inappropriate, surprisingly deep, and utterly hilarious anti-hero: Peacemaker. That’s right, HBO Max finally dropped the hotly anticipated full trailer for Season 2 of James Gunn’s Emmy-nominated series, and the internet basically exploded. If you somehow missed the first season (and seriously, what have you been doing?! Spoilers ahead if you plan to fix that oversight), let’s quickly rewind. We last left Christopher Smith, a.k.a. Peacemaker, after a truly bonkers journey. Surviving a near-fatal shooting (thanks, Bloodsport!), he got roped into …  ( 4 min )

"Fat interfaces don't just bloat your code. They quietly make it fragile over time." --- Me, after untangling a bug in a repository base class If you read my Liskov Substitution Principle article, you've seen how code can look clean and still fail when a subtype doesn't behave as expected. Interface Segregation is often the next fix you need when abstractions grow too broad, and implementations drift away from shared behavior. The idea is simple: Interfaces should describe only what an implementation genuinely supports. If a class must implement methods it does not need, you do not have a shared behavior. You have a catch‑all contract that forces unrelated responsibilities into one place. Over time, this leads to empty methods, NotImplementedExceptions, and runtime surprises instead of pre…  ( 5 min )

Ever watched a perfectly fine query turn into a 30-second nightmare in production? Yeah, me too. Usually, it's JOIN operations hitting tables without proper indexes, forcing full table scans instead of quick lookups. I recently tackled this exact problem with an e-commerce query that was killing performance. Here's what I learned and how you can fix it fast. SELECT c.customer_name, o.order_date, p.product_name, oi.quantity FROM customers c JOIN orders o ON c.customer_id = o.customer_id JOIN order_items oi ON o.order_id = oi.order_id JOIN products p ON oi.product_id = p.product_id WHERE o.order_date >= '2024-01-01' AND p.category = 'Electronics' AND c.region = 'North America'; This innocent-looking query was scanning entire tables for every JOIN.

🚀 Explore More Possibilities with React Hooks? ReactUse.com provides you with well-designed custom Hooks to double your React development efficiency! Before React 18, React always rendered synchronously, meaning that once rendering started, the entire process could not be interrupted. But React 18 introduced concurrent rendering, allowing React to pause and resume during the rendering process to handle higher-priority tasks (like user interactions). Although this mechanism improves the user experience, it also brings a new problem: when React pauses during rendering, the external data source might change, causing different components in the same render to see different data snapshots, leading to a UI tearing phenomenon. Let's first understand the tearing phenomenon through an example: imp…  ( 6 min )

In the age of AI, LLM , machine learning and agentic AI , it is a waste of resources if we did not leverage on AI or in this particular scenario LLM to speed up tedious documentation process. Generally, this is my personal approach that I wanted to use: Due to space constraints, I will focus on documentation parts only. I gather required information for the project. All relevant information is then fed to any LLM to generate documentations. I used Claude and Grok to generate documentations. Sometimes I chained the LLM output and inter-interrogate the …  ( 4 min )

When you start working with Python, one of the first recommendations you’ll hear is to use a “virtual environment.” But what exactly is a Python virtual environment, and how does it work under the hood? Python projects often rely on third-party libraries. If you install packages globally, different projects can end up fighting over package versions. This is called “dependency hell.” For example, Project A might require requests==2.25, while Project B needs requests==2.31. Installing both globally can cause conflicts and break your projects. A virtual environment is an isolated workspace for your Python project. It lets you install packages locally, so each project can have its own dependencies, regardless of what’s installed elsewhere on your system. When you create a virtual environment (…  ( 5 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. My css art was built around a typical work day, just a pictoral representation of a day doing work. I went through the css prompt for the hackathon and brainstormed on what I could build to showcase this. The code is available: https://github.com/Cruxcodes/CSS-Office-Art Live View: https://office-css-art.netlify.app/ It was a brain teasing journey. I had to zoom in and zoom out constantly to make sure each border was round enough or to discern if the div had to be closer or not. Linear gradient: Depending on your skill with css, you already know how linear-gradient works with css.

Hello dev community! 👋 Where it all began My passion for technology started out of pure curiosity. Growing up, I was always fascinated by computers. But it wasn’t until university that I realized software development could be more than just a skill — it could be a powerful tool to change lives. Starting with mine. My first "Hello, World!" Like many others, I started with HTML and CSS. But things really took off when I discovered Laravel and React Native. These two frameworks became the foundation of my career, allowing me to build full web and mobile applications with real impact. Over time, I evolved into a fullstack developer — capable of designing, building, and delivering complete solutions, from scratch to production. Real problems, digital solutions One of the things I’m most proud of is using code to solve real problems in my community. Whether it's a logistics tracking system, a disaster alert app that sends SMS to citizens, or a price comparison platform for everyday products — my mission is simple: Beyond the code For me, development is more than just writing code. It's about understanding people, solving problems, and creating meaningful experiences. That’s why I’ve also been exploring design, user experience, technical leadership, and even entrepreneurship. What’s next? I’m always open to new challenges and collaborations. I'm especially passionate about building social impact digital products, contributing to the tech community, and strengthening the developer ecosystem in Mozambique and across Africa. Thanks for reading this far! 🚀 “Code is poetry. And every poem has a story behind it.”  ( 4 min )

Olá, comunidade dev! 👋 Sou Arnaldo Tomo, desenvolvedor fullstack de Moçambique 🇲🇿, e hoje decidi compartilhar um pouco da minha trajetória com vocês. Sempre acreditei que cada linha de código escrita carrega um pedaço da nossa história — e essa é a minha. Onde tudo começou Minha jornada na tecnologia começou por curiosidade. Cresci fascinado por computadores, mas foi só mais tarde, durante a universidade, que percebi que desenvolver software poderia ser mais do que uma habilidade — poderia ser uma carreira capaz de mudar vidas. A minha, inclusive. Primeiro "Hello, World!" Comecei com HTML e CSS, como muitos de nós. Mas foi com Laravel e React Native que me encontrei. Essas duas tecnologias me deram a base sólida que tenho hoje para construir aplicações web e mobile que impactam diretame…  ( 4 min )

Relay is a GraphQL client built by Meta, designed for large-scale, high-performance apps. Unlike more flexible alternatives like Apollo, Relay enforces stricter rules for how you write queries and manage your local store — which means fewer hidden bugs, but a steeper learning curve. One of Relay’s biggest selling points is its battle-tested, “black-box” implementation of bidirectional pagination. If you’ve ever used it, you’ve probably wondered: What actually happens behind the scenes? How does Relay merge pages when you scroll up and down at the same time? Bidirectional pagination is powerful — but it can feel like magic. Let’s break it down. Before we get into the bi in bidirectional, let’s start with the basics. When you’re dealing with huge lists — like your Twitter/X feed or a WhatsA…  ( 11 min )

🚀 I Built a Library That Auto-Generates TypeScript Types from Laravel Models Hey dev community! 👋 I'm Arnaldo Tomo, a developer from Mozambique 🇲🇿, and I want to share with you a library I built to solve a problem that had been bugging me for ages in full-stack development. Like many of you, I frequently work with Laravel on the backend and React/Vue on the frontend. And I kept running into the same annoying situation: I'd create a model in Laravel I'd need to manually recreate the corresponding TypeScript interface Every time the model changed, I had to remember to update the TypeScript I'd inevitably forget, causing bugs in production I kept thinking: "There has to be a better way to do this!" After yet another afternoon lost debugging an error caused by outdated types, I decided: …  ( 6 min )

This is a submission for the World's Largest Hackathon Writing Challenge: After the Hack. It started with a simple idea — “I need a recipe app that doesn’t live in 47 open tabs and random notes.” Now, here I am post-hackathon with something way bigger than I imagined. I’ve got two exciting (and slightly chaotic) plans for MyMealMind: The All-In Service Plan Continue evolving MyMealMind into a full-blown platform. Add more community features, pro perks, gamification, and SEO-ready tools. Turn it into a go-to hub for food lovers, chefs, and kitchen pros. The Open Source Template Plan Polish the code and docs. Launch MyMealMind as a reusable template for anyone who wants to build their own recipe-powered platform. Think of it as a digital starter pack for food-tech projects. And who knows — maybe I’ll end up doing both. (Because sleep is overrated, right?) Building fast doesn’t mean skipping quality — just means you lean on the right tools (Bolt, you legend). Supabase + RevenueCat = chef’s kiss for scaling with auth, payments, and gated content. Design + Dev = magic when you stop fighting with yourself over button colors at 2 AM. Sharpened my frontend skills Got hands-on with Stripe + RevenueCat integration logic Built real features that scale (and didn’t crash... much) Joined the world’s coolest dev challenge (shoutout Bolt.new!) The hackathon might be over, but I’m just getting started. Whether MyMealMind becomes a viral app, a dev boilerplate, or both — I’m excited. And hungry.  ( 4 min )

Hi folks, I recently invented and open-sourced a new data structure called the Conjoined Tree. It’s designed for multi-dimensional data modeling—think pivot tables, OLAP cubes, or feature stores—where operations like sorting, filtering, or inserting can be done along any axis, without needing to shift the whole structure. Instead of one root like a traditional tree, it has two or more root nodes (like rows and columns), and all share the same leaf nodes. It scales up to N dimensions and supports sparse data naturally. 🔗 GitHub: https://github.com/esuryadi/conjoined-tree 📝 Article: https://www.linkedin.com/pulse/tree-two-roots-new-data-structure-multi-dimensional-thinking-suryadi-czycc 📚 Spec: https://edsuryadi.atlassian.net/wiki/external/NzM1Mjk1NDUwOWU4NGIwZDg5MGQxYWMzMTdhN2M4YWM Would love feedback or collaboration ideas.

Yesterday, I asked GPT-4 to help me write a work email to a colleague. The response was technically perfect: clean grammar, polished structure, polite tone. But something felt off. It lacked the subtle understanding of our working relationship—the accumulated history, unspoken dynamics, and tone adjustments I’ve learned over time. It felt sterile. Here’s the fundamental problem: Current LLMs operate in isolation. Each conversation exists in a vacuum. They don’t remember yesterday’s context, adapt to our evolving needs, or grow with us over time. This isn’t a technical limitation — it’s an architectural decision. And it’s the wrong one. Human intelligence builds on context. You don’t reintroduce yourself to a friend every time you meet. Context-aware AI should work the same way. Traditional…  ( 5 min )

Introdução Desde a Grécia Antiga, filósofos têm buscado reduzir a complexidade natural a princípios simples. Demócrito (c. 460–370 a.C.), por exemplo, foi um pioneiro do materialismo filosófico e tentou explicar o cosmos sem recorrer a mitos. Segundo sua visão, toda a matéria é composta por partículas mínimas e indivisíveis chamadas átomos, que se movem e se rearranjam no vazio. Para ele, diferenças entre substâncias (como a diferença entre terra e água) dependiam apenas do formato e da disposição desses átomos. Embora nossa ciência moderna descreva a matéria com mais detalhes, a essência dessa ideia, que sistemas complexos surgem da combinação de partes simples, permanece influente. Em paralelo, a computação lida com sistemas complexos que precisam ser construídos a partir de componente…  ( 10 min )

I spent ~30 minutes wondering why my dev containers weren’t seeing the Docker engine running. I was about to reinstall everything when I realized I had installed VS Code via Flatpak. As we all know, Flatpak apps run in a sandbox, so vscode has no access to /var/run/docker.sock by default Solution: Takeaway: Before debugging like crazy, double-check how your app is installed — sandboxed formats like Flatpak can break common development workflows.  ( 3 min )

This is a submission for the World's Largest Hackathon Writing Challenge: Beyond the Code. When I joined the World's Largest Hackathon, I was thinking: “Cool, I’ll build a little recipe app.” What actually happened? I ended up pulling late-night coding marathons, becoming best friends with Bolt (my AI copilot), and discovering an amazing global community of builders just like me. Bolt.new, my 24/7 coding buddy — From tricky logic to naming variables like “authTokenThatActuallyWorksThisTime”, Bolt had my back. No judgment. Just solutions. @addyosmani , you're a legend — Your tweet pulled me into this whole wild ride. I owe you coffee. IRL MVPs — My friends cheered me on like I was in the finals of Iron Chef... except I was cooking up JSX and Tailwind classes. Devpost + Discord = 💯 vibes — Every announcement felt like a hype squad cheering me on. Even when I broke the build. Again. "Wait, I just built that?!" moments — Integrating RevenueCat + Supabase + Netlify with edge functions, subscriptions, gated logic… me one month ago wouldn’t believe it. This hackathon gave me way more than an app. It gave me confidence, growth, and a weird obsession with improving UX. I shipped something real. I met cool people. And I proved to myself that I could do hard things—with a side of fun and caffeine. Catch you at the next one 🚀 — Dmitriy Check out MyMealMind on Devpost  ( 3 min )

Most developers approach AI coding tools like magic wands, throwing vague instructions at them and hoping for optimal results. However, developers who consistently achieve excellent outcomes from AI follow a structured methodology. Providing unclear instructions like "Hey Claude, can you make this payment flow better?"

Introduction In today’s cloud-driven world, securing file transfers is critical for organizations working with sensitive data. Azure provides a powerful way to isolate traffic, enforce access policies, and maintain secure communication between resources. One common use case is setting up a subnet specifically for SFTP traffic and locking it down with a Network Security Group (NSG) that controls which ports and protocols are allowed. In this hands-on lab, you’ll simulate a real-world scenario where a finance department needs a dedicated subnet for SFTP file transfers. You’ll create a subnet on an existing Virtual Network (vNet), deploy a custom Network Security Group, and restrict traffic to port 22 for secure FTP. This project strengthens your practical understanding of Azure networking …  ( 5 min )

Alright, here's a disclaimer... By the end of this article, you'll probably be in love with FastAPI. Now, this isn't sponsored (actually, I wish it were), but I wrote this because I recently used FastAPI for a project and loved every bit of it. I also found out that there weren't many engaging resources available for FastAPI. They say project-based learning is the best. So for this article, we'll do something fun while still learning about APIs. I'm a LinkedIn fan, but most bios sound corporate and sometimes like lies.

Over the last few months I've been working on a new programming language called Dassie that compiles to .NET CIL. It started as a project to learn about compiler development, but it's slowly been taking shape and getting more features. It's still very early in development and doesn't have a whole lot of features yet, but you can already do some basic stuff with it. The compiler is located here, documentation and code examples can be found here. Here is "Hello World" in Dassie: println "Hello World!" This uses the built-in function println, but since Dassie is .NET-based, you can also use the Console class: import System Console.WriteLine "Hello World!" Assuming you have installed the Dassie compiler and the above code is contained in a file called hello.ds, it can be compiled using the …  ( 4 min )

After 18+ years in engineering, from COM and MFC to SwiftUI and CoreML, I’ve learned that deep technical foundations don’t expire—they evolve. Here’s how I transitioned from legacy code to AI-powered mobile apps, and why I believe now is the most exciting time to be a developer. I started my journey writing C++ in Visual Studio, debugging MFC windows, and working with ATL COM and DirectShow. Back then, performance and memory efficiency weren’t just best practices—they were survival skills. Those same skills now guide how I build modern apps with machine learning. Whether I’m optimizing a CoreML model on iOS or embedding TensorFlow Lite on Android, I fall back on the same principles: minimize latency, handle edge cases, and test like it’s production. Over the years, I’ve built and shipped a…  ( 4 min )

“If your NFT reveals everything to everyone, you’re not tokenizing real-world assets, you’re creating digital billboards In today’s NFT world, all metadata and ownership history live in plain sight. That openness works for profile pictures and art drops, but it kills adoption for high-value use cases- property deeds, medical records, or patent licenses, where privacy is non-negotiable. Standard NFTs expose every detail: Metadata leaks asset specifics (location, valuation, personal data). Permanent history binds sensitive information to a public ledger forever. Crawlers and bots can index and exploit this data, undermining confidentiality. For tokenizing a house deed or a patient’s medical summary, you need privacy at the protocol level, not just an off-chain access control list. Privac…  ( 4 min )

Modern applications thrive on fast and efficient communication. While JSON has long been the go-to format for data exchange, many large-scale tech companies are now rethinking their choice. One such example is Atlassian, which made a strategic shift from JSON to Protocol Buffers (Protobuf) to optimize performance and reduce payload sizes across services. Their motivation? Faster API responses, smaller data transfers, and better compatibility for growing systems. In this blog, we’ll break down what JSON and Protobuf are, compare their strengths and weaknesses, and walk you through how to use Protobuf in a Node.js project. If you're wondering whether it's time for your project to evolve beyond JSON, this guide is for you. JSON (JavaScript Object Notation) is a lightweight, human-readable dat…  ( 5 min )

We've all used Python lists or arrays in code at some point. Counting the number of items in a list with len() seems straightforward—and for most cases, it is. But when you work with nested lists, arrays from the array module, or third-party structures like NumPy arrays, things can get murky. How do you accurately measure length across nested or specialized array structures? In Python, the built-in len() function gives you the top-level size in a blink. For multidimensional data, modules like NumPy expose attributes such as .shape or .size, letting you inspect dimensions directly. Understanding these methods can prevent bugs, simplify debugging, and help you pick the right tool for the job. The len() function is the go-to method for most collections in Python. It returns the number of item…  ( 7 min )

Introduction Over my experience of building and scaling platforms for several teams, I have learned a valuable lesson: Platform engineering can only work if it serves developers, not just architecture charts. It is easy to get carried away with the ambition of solving every possible future use case. But if your platform can not solve the problems you face today, it will not be adopted at all for the future. Obviously, I have also made some of these mistakes myself. I have also seen them repeated at companies undergoing enterprise modernization. And in every such case, the consequences were clear: wasted time, frustrated developers, and delayed product delivery. Based on my experience and to help my audience, I have summed up the major platform engineering mistakes you need to know and …  ( 6 min )

Many new engineers get confused when trying to understand how a CPU works. Inside that chip lies a control unit, the brain behind all the actions. One of the easiest ways to build and manage this control unit is through MCP, short for Microprogrammed Control Processor. This article walks you through each part of how MCP works, step by step. The control unit in a CPU decides how the processor moves data, performs actions, and finishes tasks. MCP makes this control unit programmable. Instead of using complex wires and circuits for every signal, MCP stores control steps in a memory. The processor reads these steps and performs them in order. Many engineers prefer mcp architecture for its clarity and ease of updates. You don’t need to change hardware when you want new control logic. You just c…  ( 5 min )

In the world of micro-services, load balancing is a cornerstone to achieve scalability. There are various load balancing algorithms that distributes incoming traffic to multiple servers. This prevents a single server from becoming a bottleneck and ensuring quick response time and less outage. Among multiple load balancing algorithms consistent hashing is an powerful technique of load balancing Imagine a simple scenario with three servers (A, B, C) and a traditional load balancer using a round-robin or modulo-based approach. When a request comes, it is directed to a server based on a simple algorithm. This works fine until you need to add a new server (D), remove an existing one or a server crashes down due to some technical issue. With traditional methods, adding or removing a server often…  ( 7 min )

Have you ever been viewing a README on GitHub that blinds you due to a white background when you're in dark mode? Or had an image that didn't quite look right in dark mode due to the difference in background colors? Well suffer no more and implement images in your README best suited to the users color scheme. To achieve this, you'll need two images - one suitable for display in a light color scheme, and one for dark color schemes. Next, you'll want to include the following code in your README: In the above code, we're using a picture element to allow us to display a different image dependent on the users preferred color scheme. Our source element defines the image we'd like to use for dark mode. The image element is what the README will default to if there is an issue with supporting the picture element, or none of the source tags are applicable. In the example above, we are using the image element to define the image we want to use in light mode and the image we want to be our default image should there be an issue rendering any of the source images. We could even take this a step further and define images for light and dark mode, and then a seperate image as our default backup image: And that's it! Now your README file will read the users preferred color scheme and display an image chosen for that theme. Want to see an example in action? Check out my example repository below: kera-cudmore/example-light-dark-github-readme-images You can emulate a color scheme in Chrome by opening the Command Menu (Ctrl + Shift + P or Cmd + Shift + P) and then typing in emulate CSS prefers-color-scheme:dark and then enter.  ( 4 min )

When we try to improve user experience for a website, good design and nice flow definitely matter. But what else should be also taken into account?

Let's be honest, nobody needs to write a polyfill for promise these days. Most of us only look for it when we start preparing for interviews. Promise polyfill is among the most common questions asked in JavaScript interviews. As a consequence, there are endless blogs on this. So why am I writing this? Well, I found that most of them have implemented Promise wrong! Most common mistake that I find in these implementations is that they return this. However, if you go through MDN docs, it clearly states that then returns a new Promise. So, in this post, I want to take you through my journey on what I feel is the correct implementation of promise. Let's start by defining a basic Promise class. type ExecutorFn = ( resolve: (data?: T) => unknown, reject: (reason?: unknown) => unknown, ) =>…  ( 14 min )

Check out WebLines on the Chrome Web Store and follow along with the story below. While working on a complex design project recently, I found myself obsessing over alignment—tweaking absolute positions and spending more time than I’d like to admit, and then, half-jokingly, I told my teammates: That random joke sparked an idea: I immediately searched the Chrome Web Store, and as expected, someone had already thought of it. WebLines is a simple Chrome Extension that allows you to draw horizontal or vertical lines across any webpage. These lines help you visually verify whether elements are aligned properly. No more squinting or nudging with guesswork. You can: Draw multiple lines anywhere on the screen Customize line color and opacity Remove lines easily Manage everything from a clean, user-friendly popup It’s designed to be lightweight, intuitive, and genuinely helpful. Something I wish I had when I was aligning those divs. 🚀 Try WebLines WebLines from the Chrome Web Store WebLines started as a random joke, but turned into a tool I now rely on whenever I need to check visual alignment. It’s simple, reliable, and does exactly what I built it for. If you’re a developer or person who values precision, give WebLines a try, and if you do, I’d love to hear your feedback. Let me know how it felt using it so I can keep improving it for everyone.  ( 4 min )

A Go module is a collection of Go packages stored in a directory with a go.mod file at its root. This file defines the module’s path and its dependencies. It allows developers to version, upgrade, and manage dependencies cleanly. Key Files go.mod: Contains the module name, Go version, and required dependencies with their versions. go.sum: Maintains checksums to verify the integrity of modules used. Basic Commands go mod init : Initializes a new module. go get @: Adds or updates a dependency. go mod tidy: Cleans up unused dependencies and adds missing ones. go build / go run / go test: Automatically resolves and uses modules. Benefits No need for GOPATH. Clear version control and reproducibility. Easier to work across multiple projects. Example go mod init github.com/username/myproject go get github.com/gin-gonic/gin@v1.9.0 This will create a go.mod file and fetch the specified version of the Gin web framework. Go Modules make dependency management in Go modern and efficient, especially important as projects grow in complexity.  ( 3 min )

Over the past two weeks, I’ve been working on a backend API project using FastAPI. The goal is to build a solid foundation for user authentication and a file management system. Initialized a FastAPI project with virtualenv and managed dependencies in requirements.txt. Configured environment variables with python-dotenv for things like SECRET_KEY and DATABASE_URL. Created the User model using SQLAlchemy with fields including id, email, hashed_password, and status flags. Implemented JWT-based authentication including user registration, login, and token refresh. Built user endpoints (/register, /login, /me) for managing user actions. Added dependency injection for database sessions and authentication in the routes. Wrote basic tests for authentication endpoints. At the end of week one, the API supports user registration and login, returning JWT tokens for authorized access. Added a File model linked to users, storing file metadata such as filename, hash, and upload date. Created file endpoints to upload, list, and delete files (/upload, /list, /delete/{file_id}). Handled file uploads with python-multipart, storing files on disk using unique filenames. Computed and stored SHA-256 hashes for uploaded files to ensure integrity. Restricted file access based on user authentication, enforcing ownership rules. Implemented validation for file size and allowed extensions. Started writing tests for the file management functionality. Moving forward, I plan to: Enhance file validation and error handling. Add support for user roles and permissions. Integrate background tasks for file maintenance using Celery. Improve test coverage and add documentation. The project is open source and available on GitHub: Task Automation API Feedback and contributions are welcome. If you’re interested in backend APIs, FastAPI is a great framework that makes building async, secure APIs straightforward. This project is a good way to practice authentication, file handling, and database relationships. Thanks for reading!  ( 3 min )

Ahoy! Today we are going to look into some basic concepts of Object Oriented Programming. Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code: data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). First things first, what's a class? Think of a Class as a blueprint. It's not a person, but it describes what makes a person. For instance, a Human class would be a blueprint defining that all humans have properties like a name, age, and eyeColor. So if a Class is the blueprint, what are you? You, my friend, are an Object. An object is a real, living, breathing instance created from a class. While the Human class is the idea, you are the implem…  ( 7 min )

What makes a data structure “beautiful”? Some say simplicity. Some say power. Some just admire how elegantly it solves a real-world problem. In this article, we’ll explore three data structures often praised as beautiful by competitive programmers, algorithm geeks, and functional programming fans. From mathematically sound hash tricks to mind-bending tree structures, they’re not just smart—they’re aesthetically satisfying. Let’s dive in. Inspired by this answer on Zhihu (in Chinese), the modular hash tree (a.k.a. “膜质数哈希树”) is a clever fusion of hashing and tries that tackles one of hashing’s biggest weaknesses: collisions. Let’s say your hash function is h(x) = x % 17. Both 19 and 36 return 2. Boom—collision. Traditional solutions: Chaining: Store a list at each hash slot. But worst-case …  ( 5 min )

CSS can feel tricky when you're starting out, especially when things just “don’t align right” or “spacing feels off.” But once you master the Box Model, understand display properties, and learn how to work with inline vs block elements, everything starts making sense.

Redis is often used as a high-performance cache in front of MySQL to reduce latency and database load. But what happens when your MySQL data is updated — and Redis isn’t? This can lead to data inconsistency, one of the most common and frustrating bugs in distributed systems. In this article, we’ll explore: What causes cache inconsistency between Redis and MySQL Proven strategies to maintain consistency How to test and validate these strategies locally Here’s a typical setup: You query Redis for a value. If it’s a miss, you fall back to MySQL. The result is written back into Redis for future access. Now suppose the underlying MySQL data changes — a user updates their profile, or a product price is modified. If Redis still holds the old value, your system serves stale or invalid data.

(Първо публикувано на 16.01.2017) Е, стигнах и до разглеждането на някои “brute force” алгоритми! 😉 Какво представляват тези алгоритми? Общо взето при тях просто пробваме всички възможни решения докато не стигнем до такова, което… ами… работи. Например ако играем шах, brute force подходът за победа би бил да пробваме *всяка *комбинация от ходове докато не спечелим, без да обръщаме внимание на подредбата на фигурите (да, дори пешката в началото, която няма шанс да стигне до царя, ще бъде преместена). Това, разбира се, би отнело прекалено много ресурси и време, но показва как точно работи един brute force алгоритъм. Сортирането чрез селекция (или “Selection Sort”) е отличен пример за такъв вид алгоритъм и си струва да го знаете. Преди да започна да пиша по темата, мога да ви спестя доста вр…  ( 6 min )

Recently, I started interacting with many DApps for DeFi, airdrops, or NFT exchanges.

And is the contract truly verified in such cases? Let’s break it down below. let's start with some context: The concept of upgradable smart contracts on Ethereum began emerging around 2017, with more formal and secure patterns being adopted by 2018. Many decentralized applications (DApps) started using this pattern to prevent and mitigate vulnerabilities that could appear in the future. Upgradable smart contracts follow a simple architecture: A proxy contract holds the data (storage) An implementation contract contains the bu…  ( 4 min )

Not a single response to the 20 emails I sent to 10 different people yesterday. And guess what? Today's their holiday. Perfect timing, right? But wait, there's more. The administration, in their infinite wisdom, decided registration day was the perfect time to introduce some mysterious extra charges. I have everything they asked for, the payment is already made, but apparently, that's not enough anymore. It's 7 PM now. Instead of being registered and ready for the semester, I'm sitting here with a headache that could power a small city. Here's what I've learned: sometimes you can do everything right and still lose. Sometimes the system is so broken that your preparation becomes irrelevant. Sometimes bureaucracy exists just to remind you that logic has left the building. Tomorrow I get to try again. Maybe the bank will remember how email works, maybe the administration will explain their surprise fees, maybe everything will magically work out. Or maybe I'll just add another chapter to this ongoing comedy of errors. Either way, this headache and I are calling it a day. This is part of my daily documentation of the chaotic journey through college and building projects. Some days are productive, some days are like this one.  ( 3 min )

Twenty years ago, owning healthcare software meant owning servers, backups, and data. Clinics invested heavily upfront, downloaded software onto local PCs, and navigated complex annual maintenance contracts. Fast forward to today, the world of healthcare has completely changed. The introduction of digital tools in almost every workflow has opened the gates for clinics to achieve optimal efficiency while spending less. Now, SaaS platforms are giving the industry a new way to handle daily medical operations. It is cloud-first that works on a pay-as-you-go model, keeps systems up to date with the latest tech, and is remotely accessible. But that doesn't mean they automatically replace licensed software in every context. In fact, global healthcare SaaS market is projected to reach USD 77.…  ( 8 min )

Have you ever poured your heart into a resume, hit "submit," and waited… only to hear nothing back? That frustrating silence, the endless second-guessing, the late-night tweaks wondering if your resume was even seen? I’ve been there. And I’m betting you have too. I’m Himanshu Jain, a final-year Computer Science student from India, and I built IntelliCV because I was done with the resume black hole. I wanted a tool that doesn’t just spit out a score or generic advice—it gets the job search grind and gives you clear, actionable feedback to stand out. Here’s why I created IntelliCV, how I built it, and why you should join the waitlist to try it. It’s 2 a.m. You’re tweaking your resume for the hundredth time.

Intro Have you ever thought or wished that AI assistant like Claude, ChatGPT or your own AI assistant could actually open up your gmail and reply to your customers queries, accessing files from Google drive, updating task status on jira, sending notification on slack when a task status gets updated - without you writing a mountain of glue code? That's exactly the problem what MCP(Model Context Protocol) solves. What is MCP in one line? MCP is an open protocol(standard) that lets any AI application talks to any external tool, services or data resources in a single, secure and standardized way. The pain MCP fixes Before MCP, every new itegration looked like this: Build custom API wrappers Handle auth, rate-limits Repeat these steps for every LLM provider USB-C analogy You can think of MCP like a USB-C port for AI applications. Just like USB-C provides a standardized way to connect your devices to various peripherals or other devices, MCP provides same kind of standardized way to connect AI models to different data resources and tools in plug-n-play manner. Under the hook working Simple example For example, you can ask following: "Show last five emails which I recieved on my gmail account." Security & Governace MCP servers run locally or in your VPC; credentials never leave your machine so much lower chances of leaking. Each tool has its own JSON-Schema inputs, so the malicious request can be blocked before even they are executed. MCP = Universal protocol for all AI applications Read official docs here. https://modelcontextprotocol.io/docs/learn/architecture  ( 3 min )

Hi there, I’m Jaideep Parashar, and this is my official hello to the dev.to community! I didn’t come from Silicon Valley. I didn’t have millions in funding. I didn’t even have a backup plan. What I had was a laptop and a burning desire to do something meaningful with Artificial Intelligence. Today, I run a company called ReThynk AI, I’ve authored 40+ books on AI, and I’m on a mission to help 10 million people move from AI fear to AI fluency. But how did I get here? 🔁 From Stability to the Unknown I had seen how people around me were afraid of AI, thinking it would replace jobs, confuse them, or stay out of reach. I wanted to change that narrative. So I started learning, writing, and building. 🧠 What I Learned Along the Way You don’t need to be a developer to start using AI effectively. Building something valuable isn’t about tools — it’s about clarity, consistency, and courage. I turned prompts into books, books into systems, and systems into solutions. 🎯 Why I’m Here on dev.to Here’s what you can expect from my posts: Prompt Engineering for business, productivity, and creativity AI Workflows using ChatGPT, Python, and No-Code tools Real case studies from ReThynk AI Lab Lessons from writing 40+ AI books AI strategies for solopreneurs, educators, developers, and creators And some behind-the-scenes truths — wins, failures, beliefs 📌 What’s Coming Next?

In a typical ASP.NET Core application, you might be tempted to place a lot of logic in your controllers or services. As the app grows, this can lead to: Controllers bloated with business logic Services tightly coupled and difficult to test A tangled web of dependencies that becomes a nightmare to maintain Sound familiar? Enter the Mediator pattern, and more specifically, MediatR: a lightweight library that brings this pattern to your .NET applications. The Mediator pattern encourages communication between objects through a central "mediator" rather than direct references. It promotes: Loose coupling between components Single Responsibility in handlers Centralised coordination of behaviour In ASP.NET Core, this means that instead of calling services directly from controllers, we send a requ…  ( 5 min )

I once opened a client’s website and immediately felt like I was transported back to the MySpace era — text overlapping images, buttons dancing on hover like caffeinated frogs, and a rainbow of font colors that screamed “I just discovered CSS!” If you’ve ever felt secondhand embarrassment for a website, you know what I mean. It’s wild how just a few bad CSS decisions can tank the credibility of your entire site. People don’t trust ugly. And if your site looks janky, they bounce — fast. So, let’s call out these rookie (and sometimes criminal) CSS mistakes that make websites look like side projects from a college dorm room. 1.

There is nothing more satisfying than building great products that entice your users. However, building a great product requires more than just coding or designing, and that's what I'm learning these days. I am one of those people who believe in building great products at great speed.

Imagine a puzzle game where you have six holes. Each hole holds a colored ball (red, blue or green). To win that round in the game, you have to sort the balls so that all the red ones come first, then the green ones, and finally the blue ones. But you can only compare two balls that are side by side, and if they’re not in the right order, you swap them. You go through the row of balls, checking two at a time. If they’re in the wrong order, you swap them. As you repeat this process, the balls slowly move into the right positions (red moves forward, blue shifts to the back). You continue until no more swaps are needed. That is how the bubble sort algorithm works. So, what is bubble sort? Bubble sort is a type of sorting algorithm that goes through a list of items and arranges the items on th…  ( 6 min )

A child sits alone in their bedroom, asking an AI chatbot about thoughts they dare not share with parents or teachers. The AI responds with fabricated medical advice, manipulative guidance, or harmful misinformation—presented with confident, authoritative language. There are no guardrails here, no adult supervision, no safety net. As generative AI technologies become increasingly embedded in children's lives—from homework help to emotional companionship—the gap between technical advancement and safeguards grows more perilous. This intersection of childhood vulnerability and artificial intelligence presents one of the most urgent ethical challenges of our digital age: when AI systems can lie convincingly to children, who bears responsibility for protecting them from harm?

Introduction - The Struggle is Real Ever had one of those days when your code just stubbornly refuse to cooperate, throwing errors that makes no sense and you are just getting crazy trying to fix them? I bet you had! For me it happened yesterday! I was working on the backend for my project and I wanted to work with TypeScript and Express. I worked with Express before, but with JavaScript instead. So I just thought, what could go wrong? And just right then the world started to fall apart... Does TS1259: Module 'cors' can only be default-imported using the 'esModuleInterop' flag sounds familiar to you? Or what about error TS1192: Module 'cors' has no default export?

By Shivam Sunel – Performance Marketing & Web Development Expert Does Google Penalize AI-Generated Content? Google doesn’t care who writes the content. It cares about how helpful, reliable, and original that content is. In its official Search Central blog, Google says: “Using automation—including AI—to generate content with the primary purpose of manipulating ranking in search results is a violation.” So, if you're using AI to spam keywords or mass-produce low-value content — yes, you’re at risk. But if you’re using AI as a support tool and adding human oversight, Google has no issue with that. My Real-World Observation: Human-AI Collaboration Wins 100% human-written content 100% AI-written content Human + AI-assisted content (edited, SEO-aligned, and fact-checked) Guess what performs best? You get the speed of AI and the trustworthiness of human refinement. It ranks better, engages users longer, and gets shared more often. What Happens If You Rely Only on AI? ❌ Factual Errors: AI doesn't verify sources. ❌ Generic Content: Lacks depth and personalization. ❌ E-E-A-T Risk: Google doesn’t see any proof of real experience, expertise, or trust. Bottom line? What Actually Helps Google Rank Your Content Search Intent Matching Content Depth Internal Linking E-E-A-T On-Page SEO AI Content in 2025: A Tool, Not a Replacement Keyword clustering Outlining blog structures Explaining technical ideas in simpler ways Generating FAQs and headlines But I never publish AI content without editing.

WTF is this: Serverless Architecture Ah, the sweet, sweet thrill of not knowing what the heck someone is talking about when they throw around tech buzzwords. Am I right? Today, we're tackling a doozy: Serverless Architecture. Don't worry, I won't make you set up a server farm in your garage or anything (although, if you have the space, go for it). What is Serverless Architecture? Serverless Architecture is a way of building and running applications without, well, servers. Or at least, without worrying about them. Think of it like a restaurant.

This project is a great example of how we can apply basic yet powerful machine learning concepts to solve real-world problems without diving into heavy or complex algorithms. Many Android apps request multiple permissions like access to your location, SMS, or microphone. While some are necessary, others may indicate malicious intent. So I asked: "Can we detect malware just by analyzing the permissions an app asks for?"

Ever wondered if you could predict the price of Dogecoin with the power of modern web tech and a sprinkle of meme magic? Me too! So I built a dashboard that does exactly that—using Next.js, React, TypeScript, Tailwind CSS, and FastAPI. Is it accurate? Well, it’s at least as accurate as your average crypto influencer’s tweets. 🐕 Why Dogecoin? Why This Project? Dogecoin is the only crypto with a Shiba Inu mascot and a cult following that can send it “to the moon” on a whim. I wanted to build a dashboard that predicts Dogecoin prices, looks cool, and is as easy to use as buying a meme coin at 3am. 🧩 Tech Stack (a.k.a. The Meme Machine) 1. Frontend: Next.js, React, TypeScript, Tailwind CSS (for those sweet gradients) 2. Backend: FastAPI (Python, because AI sounds fancier in Python) 3. UI Components: Custom and shadcn/ui (because why not) ✨ Features (Much Wow) - Live Dogecoin price prediction (or at least, a very convincing mock) - Interactive dashboard UI (click buttons, feel powerful) - Instantly switch between a mock API and a “real” backend - Modern design with reusable card components (so you can flex on your dev friends) 🏗️ Architecture (It’s Not Rocket Science… Or Is It?) Frontend: Next.js + React fetches predictions and displays them in a dashboard that’s prettier than your portfolio site. Backend: FastAPI provides a /predict endpoint for real or meme predictions. Toggle a variable to switch between “real” and “mock” predictions. It’s like flipping a coin, but with more code. 🔗 Try It Yourself! Want to see the code or run the dashboard yourself? https://github.com/TROJANmocX/Dogecoin-Dashboard Remember: If this dashboard predicts Dogecoin will reach the moon, it’s probably just reflecting my hopes and dreams. 🚀🌕 Much wow, very finance, such dashboard.”  ( 4 min )

Introduction While studying for AWS SAA (Solutions Architect Associate) certification, I encountered the question "What are ephemeral ports?" So I decided to research and summarize this topic! Ephemeral ports are dynamically allocated port numbers temporarily used by client-side applications. As you know,The word "ephemeral" means "temporary" or "transient," and true to its name, these are short-lived ports that exist only during the duration of a communication session. While server applications typically listen on fixed well-known ports (port 80 for HTTP, port 443 for HTTPS, etc.), client-side applications need different port numbers for each connection. This is where the operating system automatically selects and assigns unused port numbers - this mechanism is what ephemeral ports are …  ( 4 min )

Your API is Cute, But Where's the Real Backend? - Part 2 🤔 In Part 1, we ran the kitchen - took orders, routed them to the right chefs, and served our hungry users. A guy in a stained T-shirt walks through the back door claiming he's "new kitchen staff." In a restaurant, identity matters. So does it in your backend. Think of JWTs (JSON Web Tokens) as guest passes. Without one, you're not getting a seat, let alone the special menu. 🧂 How it works: // User logs in → you give them a signed token { "userId": "12345", "role": "admin", "exp": 1724102400 } // Client sends it in every request Authorization: Bearer // You verify it on every incoming request 🔐 No token, no service.

The picture of this article is the output of Claude, using a local MCP server that gives it the output of the ls -l command on a given path. Notice how the LLM likes to praise me, exaggerating a bit, In my opinion this is just a way to keep your users hooked on their product. Who doesn't like to be praised and approved with everything they say, right? :D Hello everyone, I wanted to write an article on MCP servers since I just written one in Python last week. Theory​ MCP stands for Model Context Protocol, and it is a standardized protocol designed to connect LLMs with tools, resources and prompt templates.

Dati, informazioni, conoscenza e saggezza: un viaggio attraverso il modello DIKW Ciao devs! 👋 Oggi parliamo di qualcosa che sembra astratto ma è fondamentale per come lavoriamo con i dati: il modello DIKW. Molti lo usano come se fosse ovvio, ma c'è molto di più sotto la superficie. Andiamo a scoprirlo! Cos'è il modello DIKW? Un esempio pratico: aprire un conto di risparmio Dati: numeri senza contesto 100€ Informazioni: dati in contesto Capitale: la somma di denaro depositata, ad esempio 100€. Conoscenza: azioni basate su informazioni Se vuoi risparmiare, sai quanto guadagnerai. Saggezza: comprendere il quadro generale Potresti credere che risparmiare e investire ti renderà ricco nel tempo. La saggezza implica riconoscere queste complessità e adattarsi di conseguenza. Come ha detto Alex Bennett, possiamo considerare la conoscenza come la capacità di intraprendere azioni efficaci in situazioni varie e incerte. Ma la vera sfida è raggiungere la saggezza, che richiede di andare oltre le nostre illusioni e comprendere i principi più ampi che governano i sistemi in cui operiamo. Quindi, la prossima volta che lavorate con i dati, pensate a come potete trasformarli in informazioni, conoscenza e infine saggezza. Buon coding! 🚀  ( 4 min )

Pivoting in Internal Networks: Traversing the Labyrinth Introduction In the realm of cybersecurity, gaining initial access to a network is often only the first step for an attacker. To reach their target – be it sensitive data, critical infrastructure, or specific systems – they frequently need to move laterally within the network. This process, known as pivoting, involves leveraging a compromised system as a stepping stone to access other systems that might not be directly accessible from the attacker's initial foothold. Pivoting is a crucial technique for penetration testers to simulate real-world attack scenarios, and for defenders to understand potential attack paths. This article delves into the concept of pivoting in internal networks, outlining its prerequisites, advantages, disa…  ( 7 min )

State management defines how your Angular app behaves - and how maintainable it is in the long run. Choosing the right strategy affects everything from performance to developer productivity.

🖥️Understanding systemctl: The Heartbeat of Modern Linux If you've been working with Linux systems, especially more recent distributions, you've undoubtedly come across systemctl. It's the primary command-line tool for controlling systemd, the modern system and service manager that has become the de-facto standard for many Linux distributions. But what exactly is systemctl, why is it so prevalent, and what did we use before it? Let's dive in. For decades, the traditional Unix/Linux boot process was managed by SysVinit (System V init). It was a straightforward, sequential process. Services were started based on runlevels, and scripts in /etc/init.d/ handled service startup and shutdown. While robust for its time, SysVinit had several limitations: Sequential Booting: Services started one …  ( 6 min )

Introduction: The Necessity of Locking in Database Systems In the intricate world of database management systems (DBMS), the ability to support multiple users or processes accessing and modifying data simultaneously is both a powerful feature and a significant challenge. Databases must ensure that data remains accurate, consistent, and reliable, even when numerous transactions—logical units of work involving operations like reading, writing, or updating data—are executed concurrently. This is where locking comes into play, serving as a critical mechanism within concurrency control to manage access to shared data and prevent conflicts that could compromise data integrity. Locking is essential for upholding the ACID properties (Atomicity, Consistency, Isolation, Durability) that define rel…  ( 12 min )

Introduction: The Importance of Transactions in Databases In the world of database management systems (DBMS), transactions are the fundamental units of work that ensure data is manipulated in a reliable and consistent manner. A transaction is a sequence of operations—such as reading, writing, updating, or deleting data—that must be completed as a whole. If any part of the transaction fails, the entire operation must be undone to prevent partial updates that could leave the database in an inconsistent state. This process of undoing a transaction is known as a rollback. But why do transactions get rolled back, especially when multiple operations "clash" or conflict with one another? And how does a database system decide when and how to roll back a transaction? These questions lie at the he…  ( 12 min )

The World's Largest Hackathon started with a single prompt—and ended up reshaping the way I think about building. I didn’t go in expecting life-changing revelations. I went in expecting a fun challenge, a few late nights, and maybe a cool demo by the end. But what I got was a deeper connection to the why behind my work. My project didn’t launch with a bang. It didn’t go viral or catch investor attention. But what it did do was remind me that finishing something is a win in itself. Throughout the hackathon, I learned to: Ship fast, and polish later Turn vague ideas into usable tools with Bolt.new Design for simplicity, not complexity Using Bolt.new as my foundation taught me a lot about building smart—not hard. I explored: Prompt engineering for logic flows and interfaces Rapid prototyping with AI as a partner Structuring apps with modular, testable components I got better at thinking like a builder who respects both time and user attention. That’s a lesson I’m carrying forward. The hackathon might be over, but the app is far from done. I’m not continuing development or slowly shaping it into something more polished and ready for real-world use. I'm using it as a stepping stone into something bigger because now i have learnt how to build and not just to build for building but to build with purpose. And I’m planning future builds with the same lean, idea-first approach I practiced here. Small, useful, and real. This hackathon taught me that momentum matters more than medals. That building fast is a skill. That the act of creating something out of nothing still feels like magic, every time. And that sometimes, showing up, building something honest, and hitting "Submit" is the real win. See you at the next hack. ✌️  ( 4 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space I built a dynamic and engaging intranet homepage using only HTML, CSS, and JavaScript. The interface includes a personalized welcome message that greets users based on the time of day and their name, stored locally for a consistent experience across visits. It also features a floating virtual assistant icon that opens a helpful panel with quick-access internal resources. This design provides a user-friendly, modern look while remaining lightweight and accessible without a backend. It contains again news sections, archives highlights and other thing. Link of deployment : https://frabjous-twilight-eeed40.netlify.app/ Github link with MIT License : https://github.com/Judakp/FrontendChallenge-Axero.git I started by designing a clean layout, prioritizing user engagement and usability. The first component I implemented was the dynamic welcome message, using JavaScript to greet users according to the current hour and storing their name via localStorage. This makes the experience feel personal and consistent. Next, I added a virtual assistant bubble that stays fixed at the bottom corner. When clicked, it reveals a compact panel with helpful internal links like accessing documents, contacting HR, or checking the schedule. I used smooth hover effects and light shadows to make the interface visually appealing and intuitive. I finally created news sections , archives highlights and other thing.  ( 3 min )

When I signed up for the World's Largest Hackathon, I expected late nights, last-minute bugs, and a rollercoaster of caffeine-fueled coding sessions. What I didn’t expect was how human the experience would be. Although I built my project entirely solo, I never felt like I was working in a vacuum. The global energy during the hackathon was contagious. Whether it was reading through other builders’ updates or catching the AMA replays, there was always something to keep me motivated. Even in moments of silence, I felt connected. I had the chance to attend a local satellite event in Lagos—a gaming room turned hacker den for the weekend. The LED lights were glowing, keyboards clicking, and the vibe? Somewhere between “startup garage” and “LAN party.” We passed around cookies and ice cream, exchanged stories, and celebrated small wins like fixing stubborn bugs or finally nailing down an AI prompt. It was low-key, but that shared atmosphere of creation made it unforgettable. Bolt Team – for making app development feel like alchemy. The way I could scaffold a backend and logic with simple prompts changed everything. Eric Simons & Greg Isenberg’s AMA – raw, honest, and incredibly grounding. A reminder that every big build started as a rough sketch. Discord Community – while I didn’t reach out for help directly, just seeing the energy, memes, builds, and support from fellow builders gave me the push I needed. Yes, I shipped something I’m proud of. But the real win wasn’t the product—it was the experience. The community, the chance encounters, and the late-night moments when I remembered why I love to build in the first place. If you’re thinking about joining the next hackathon: do it. Even solo, you won’t be alone. The code may be yours, but the momentum is shared. Huge thanks to everyone who made this journey unforgettable. Catch you in the next build. 🚀  ( 4 min )

SSL certificate strategy must be greatly considered when managing multiple subdomains for your website, as a business owner or a web deliver. Would it be better to buy an individual SSL certificate for single subdomain or simply procure a timesaving wildcard SSL certificate?

Introduction Git is not just a tool — it’s the lifeline of modern software development. Yet, many junior developers underestimate its power. If you don’t master Git early, you’ll soon find yourself drowning in broken branches, lost commits, and unsolvable merge conflicts. This guide covers the absolute must-know Git commands that every junior developer should engrain into their muscle memory. 1. git init What it does: Initializes a new Git repository. If you’re starting a new project, run: git init Without this, Git won’t track your project. Forget this step, and you’re just coding in the void. 2. git clone What it does: Clones a repository from a remote source. git clone When you join a team or contribute to an open-source project, this is how you grab the code. 3. git …  ( 4 min )

If you've been keeping an eye on modern web development trends, you've probably heard a lot of chatter about edge functions, edge computing, or “running your code at the edge.” No, it’s not some new punk band. It’s the next step in how we build fast, scalable applications, and it’s not just hype. So, what are edge functions? Why should you care? And how do they fit into modern stacks? Traditionally, when someone makes a request to your app, it hits a centralized server, maybe in Virginia, maybe in Frankfurt, maybe in some giant AWS data center somewhere. Edge functions are like mini serverless functions that run at those edge locations.

Yesterday, I asked GPT-4 to help me write a work email to a colleague. The response was technically perfect: clean grammar, polished structure, polite tone. But something felt off. It lacked the subtle understanding of our working relationship—the accumulated history, unspoken dynamics, and tone adjustments I’ve learned over time. It felt sterile. Here’s the fundamental problem: Current LLMs operate in isolation. Each conversation exists in a vacuum. They don’t remember yesterday’s context, adapt to our evolving needs, or grow with us over time. This isn’t a technical limitation — it’s an architectural decision. And it’s the wrong one. Human intelligence builds on context. You don’t reintroduce yourself to a friend every time you meet. Context-aware AI should work the same way. Traditional…  ( 5 min )

Let’s get this out of the way first: Git is confusing. No one picks up Git and immediately feels like a wizard. If you’ve ever stared at your terminal wondering what the heck detached HEAD means, you're not alone. Most tools do one job and do it simply. Git, on the other hand, is like a Swiss Army knife duct-taped to another Swiss Army knife. It tracks versions, coordinates collaboration, manages history, branches reality... and expects you to understand how all those parts fit together. Git makes a lot more sense once you understand how it actually works under the hood. Think of Git like a fancy key-value store. Every commit is just a snapshot of your code at a moment in time, and Git stores them as objects. Those objects are linked by hashes, not filenames. That’s why it doesn’t really c…  ( 4 min )

In the Linux world, 'Ricing', refers to the process of customizing your machine, and create a custom environment for yourself. The term 'rice' originates from the old internet slang which meant 'to make it look nice' and is now majorly used for customizing a desktop environment. The Ricing Culture, began soon after minimalist window managers like i3, or bspwm started to emerge in the early Linux days, providing users with a way to customize their entire desktop stack. Early on, this trend of customizing your desktop started to pickup and people started sharing configurations and screenshots with each other on early social platforms. Linux is the holy grail for ricing. Linux is like a modular puzzle, it is built up of small pieces that are replaceable and customizable as per the users choic…  ( 10 min )

Imagine handing the keys to your house, or even your entire neighborhood, to a global team of maintenance workers. You trust them to keep everything running smoothly, but what if some of those workers were based in a country with geopolitical tensions with yours? That’s essentially the digital dilemma the U.S. government is grappling with right now, brought to light by a recent ProPublica investigation. Last week, Microsoft announced it would no longer use China-based engineering teams to support the Defense Department's cloud systems. On the surface, that sounds like a smart, proactive move. Cybersecurity experts have been vocal about the potential risks – the specter of hacking and espionage looms large when sensitive government data is involved, even indirectly.

As a developer and content creator, I constantly write—whether it’s documentation, blog posts, email sequences, or even meta descriptions. And one thing I find myself checking more often than I expected? Word and character count. Sure, Google Docs does it. Word does it.

Microservices are supposed to be independent, autonomous, and scalable. But in reality, they often end up tightly coupled—relying on synchronous API calls, complex orchestration, and fragile dependencies. In this post, we’ll explore how to break microservice dependencies using a powerful pattern known as Event-Carried State Transfer (ECST)—or as I like to call it, Self-Contained Events. It’s a simple yet impactful idea: put all the necessary data in the event. Many microservice systems fall into a trap: they rely heavily on synchronous API calls between services to share data. This creates tight coupling, reduces resilience, and introduces latency.This API dependencies hurt reliability and scalability. Let’s say a customer places an order. The Order Service emits an event like: { "eventT…  ( 4 min )

And honestly, it's starting to feel like traditional cybersecurity methods are playing an exhausting game of digital whack-a-mole—patching here, scanning there, reacting everywhere. But what if we flipped the narrative? Instead of reacting to threats after they happen, what if AI helped us stop them before they even had a chance to begin? Sound futuristic? It’s actually a future that’s already knocking on the door—and trust me, it’s worth opening. If you’re in IT or cybersecurity (and hey, I’ve been there), you know the drill: end…  ( 12 min )

🔍 Understanding CSS Inheritance: What Gets Passed Down and What Doesn’t When writing CSS, understanding how inheritance works can help you write cleaner, more maintainable stylesheets. However, not all CSS properties behave the same way. Some are naturally inherited by child elements, while others are not—requiring you to re-declare them explicitly. In this post, I’ll guide you through: What CSS inheritance actually means Which properties are inherited by default Which ones aren't (but maybe you think they are!) A visual reference table to help you remember Some tricky exceptions and how to manage them In CSS, inheritance means that some properties applied to a parent element are automatically applied to its child elements—even if you didn’t explicitly declare them again. For example: b…  ( 5 min )

TL;DR: Two pointers is a powerful pattern for solving problems in sorted arrays. It’s faster than brute force and unlocks elegant solutions for many common interview questions. If you’ve ever seen a Leetcode solution that says “use two pointers” and thought: “Yeah sure... but why does that work?” You’re not alone. Two pointer problems look simple — but they feel like magic when you're new. So let’s break it down the way I wish someone had explained it to me: like we're pair programming side by side. Two pointers is a pattern where you use two indices (or “pointers”) to traverse an array — either from both ends or from the same direction — to solve a problem more efficiently than brute force. It’s mostly used when: The array is sorted You’re looking for relationships between elements (like…  ( 5 min )

Introduction The public website is a key asset for any company. It is where the company displays product images, promotional videos, marketing copy, customer success stories, and many more. In Azure, these types of unstructured non-relational data are referred to as blob (binary large objects). Company growth will probably translate to more site visits. Therefore, it is essential that the website content remains highly available, loads quickly, and supports features like version control and easy recovery. In this guided exercise from Microsoft, we will create and configure an Azure Storage account specifically for hosting this public content.

This post is just a quick summary of what I learned not a deep dive, just something simple to help others get started.

Con el paso de los años, estas áreas se vuelven más complejas y demandantes. Es maravilloso disfrutar la juventud, cuando muchas de estas preocupaciones aún no existen. Sin embargo, resulta difícil entender cómo muchas personas desperdician esa etapa.

In April 2022 I made a review of Haskell libraries for JSON Schema. The outcome of my research was that there weren't really any good libraries for dealing with JSON Schema from within Haskell. That was a surprising disappointment, because Haskell often has very good libraries (although they may be hard to use). The reason is that the JSON Schema specification itself isn't very well-made. I eventually gave up using any of them. Today Albert Krewinkel wrote me and told me that you can actually use AutoDoCodec to both generate and validate JSON schemas. The Haskell package autodocodec was announced in Haskell Weekly #291 in November 2021 by Tom Syd Kerckhove.

Warm organ stabs, nuanced percussion, and upbeat horn accents create dynamic layers. There's a bit of reggae in the air! That's right, I inserted some reggae in the prompt. Initially I tried ballad, or other generic stuff. But reggae totally nailed it! Especially given those weird "noise" lyrics. The AI used it both in the beginning and at the end. Fun fact: The noise lyrics NEVER MATCHED the part of the melody I envisioned, yet it turned out great! This is one of my favorite resulting songs... Hum...

Most note-taking apps claim to be "encrypted" but still have a dirty secret: they can read all your data. When we built Typelets, we decided to do things differently - using true zero-knowledge encryption where even we can't decrypt your notes. Here's exactly how we did it using just the Web Crypto API. When apps like Notion say they're encrypted, they usually mean: ✅ HTTPS encryption in transit ✅ Database encryption at rest ❌ They still hold the keys to decrypt everything We wanted to build a notes app where privacy wasn't just a marketing claim - it was mathematically guaranteed. That's why we created Typelets with zero-knowledge architecture.

When developing, you may have heard terms like linear space O(n) and constant space O(1), or seen them completing coding challenges; but what do they actually mean? These terms describe the space requirements of an algorithm and how those requirements grow as the input size increases. They're part of what's known as Big O notation, a mathematical way to describe algorithmic efficiency — both in terms of time and space. This post focuses on space complexity. Space complexity refers to the amount of memory an algorithm needs to run, including: Input space: Memory used to store the input itself. Auxiliary space: Extra memory used during processing (e.g., temporary variables, stacks, arrays, etc.). In Big O notation, we usually refer to the auxiliary space, since input space is often cons…  ( 5 min )

Hey folks, Maybe it helps someone out there who’s still in the trenches. ⸻ Just start building — even if it sucks Seriously. I kept waiting until I “understood everything” before starting a project. That was a trap. ⸻ Get good at Googling Nobody remembers everything. The real skill is knowing what to search and how to phrase it. ⸻ Keep a “dump” file I always have a random file open (mine’s called junk.js) where I test stuff, break code, or just experiment. It’s like a no-pressure sandbox — no rules, no cleanup, just play. ⸻ Console.logs are fine. But learn the debugger Took me way too long to realize breakpoints and watch values are actually easy and save you so much time. Especially when stuff gets messy in loops or async code. ⸻ If you can’t explain it, you probably don’t get it Try explaining a concept out loud — to yourself or someone else. If you stumble, that’s a clue to revisit it. Writing blog posts or rubber-ducking really helps here. ⸻ It’s okay to delete code Sometimes when I’m stuck, the fastest fix is just… deleting the thing and starting over. I used to be scared of that, but it usually ends up cleaner the second time. ⸻ You don’t need to know everything There’s so much pressure to learn every new framework or language. Truth is, you can go very far by just going deep in one stack. Don’t burn out trying to chase every trend. ⸻ That’s it for now. Not groundbreaking, just honest stuff that helped me personally.

Hey Dev Community! 👋 I'm working on a Django-based web application for a university research study that explores passphrases across different languages. I’ve built most of the core functionality, but I’ve hit a blocker I can't seem to solve and could use your help. 🧠 Project Background This is a user study platform (academic) where participants: Log in or sign up Consent to a study Complete a series of language-based passphrase tasks We use Django 5.2.1, and the app has: Allauth (for auth, but only the backend currently) Custom user flow Consent form Task-based progression (task1 → task2, etc.) ❗ Problem I'm Facing After logging in (especially in a fresh or different browser), when the user clicks “Start the Study”, they hit this: Despite having: {% csrf_token %} in the form CsrfViewMiddleware active Proper CSRF_TRUSTED_ORIGINS and ALLOWED_HOSTS Cookies confirmed in the browser get_token(request) and @csrf_protect used Still, the form POST fails on that "Start the Study" step. ✅ What Works Viewing the home page after login also works. Form displays the token correctly. CSRF cookie is generated. If I refresh or re-login, it sometimes works — it's inconsistent. 💡 What I Think Might Help Guidance on how to persist CSRF token between views properly? Is get_token(request) necessary in views? Anything to check in my session/cookie setup? 🔗 Project Info Python 3.11 / Django 5.2.1 SQLite (for now) Hosted locally (localhost:8000) CSRF Cookie: Lax, Secure = False (for dev) CSRF token is present in the form 📂 Want to Help?

General Introduction What is Reactive Programming? Wikipedia: Reactive Programming Reactive programming is a declarative programming paradigm focused on data streams and the propagation of change. It allows working with both static (e.g. arrays) and dynamic (e.g. event emitters) data flows, automatically handling updates via the Observer pattern. In essence, reactive programming is about data flow, asynchronous communication, and automatic propagation of changes. In Spring, the key difference between traditional Spring MVC and WebFlux is synchronous vs asynchronous processing. Instead of blocking to wait for a response, reactive code allows you to invoke a method and keep doing other work while waiting. Spring uses Project Reactor internally, which implements the Reactive Str…  ( 5 min )

I know I can get things done, no matter the challenge. But how do I do it effectively? That question has been on my mind for a while now. It's no longer about proving my capability to accomplish something, what's been driving me lately is a more subtle (and deeper) unease: the desire to do better! Capability Isn't the Hurdle If you work in tech, you've probably gone through the phase of learning new tools, frameworks, languages, and methodologies. In the beginning, the challenge is always about making it work. But after some time, something shifts. Execution stops being the obstacle, and a new question pops up: "Okay, I can do it. But is it actually good?" The Unease That Propels This kind of restlessness signals maturation. It's when you stop measuring your work solely by the number of co…  ( 4 min )

Hi, I'm Dhamith, a software engineer with over 2.5 years of experience. But back when I was an undergraduate, I faced the same challenge many students face today, finding an internship. These days, it's tough. There's lots of competition, few responses, and endless applications. That's exactly why I'm sharing my story. I didn't land my internship through a job portal or by sending out resumes. It came from something completely different. Here's how it happened. In the beginning, I built a few hobby projects just for fun. Simple things I was curious about or wanted to try. I didn't expect much from them, but I shared them anyway on social media. At first, I posted my work everywhere Twitter, Facebook, and LinkedIn. But after a while, I started noticing something, LinkedIn was where my work…  ( 5 min )

While working with Git branches like develop and main, it's common to frequently merge changes. But did you know that doing so with regular merges can break a linear commit history? Here's what I learned today 👇 If you keep merging from develop to main using regular git merge, Git will create merge commits, leading to a non-linear (branched) commit history. This can make git log harder to read, especially in large projects. To ensure a clean, straight commit history on main, use one of these strategies: Rebase Before Merge git checkout develop git rebase main # Replay develop commits on top of main git checkout main git merge --ff-only develop # Fast-forward only ✅ This avoids merge commits and keeps the history linear. Use Squash Merging (Optional) If you want to combine all develop changes into a single commit before merging: git checkout main git merge --squash develop git commit 🎯 Useful for condensing work into one clean commit. Use Fast-Forward Merges Only Prevent accidental merge commits: git merge --ff-only develop 🔁 Repeat this pattern consistently to keep main clean and linear — great for production branches and readable history.

Account abstraction has been a hot topic in Ethereum development for years, and ERC-4337 finally brought it to life. USDC or USDT because you lacked just a bit of ETH for gas fees, you're not alone — and ERC-4337 is part of the solution.

Introduction Launching a successful token presale is not just about having a great product or tokenomics—it’s also about building momentum, trust, and community engagement. One of the most effective ways to achieve this is by leveraging a revenue sharing model as part of your presale marketing strategy. This approach incentivizes community members, influencers, and promoters to actively participate in and promote your presale, creating a win-win scenario for all parties involved. A revenue sharing model in the context of a token presale is a system where a portion of the funds raised (or tokens sold) is distributed as rewards to promoters or referrers who help bring in new investors. This model transforms your community into an active marketing force, aligning their interests with the su…  ( 6 min )

There's been a flood of demos lately showing off how MCP servers can write WhatsApp messages or book plane tickets. Most of that feels like novelty, not utility.

Content might be pulled from the web, cleaned, annotated, and prepped by unseen hands. Yet, when the product goes live a chatbot, a new algorithm, a predictive tool credit is often centralized. The work of contributors gets buried under logos and branding.

Have you ever wished that you could learn a new language just by browsing the web? Well I know I have. About a year ago I decided that I wanted to learn Russian. Learning a new language is a slow process, so being able to spend time constantly working towards this goal is critical.

Wave provides a feature called inline assembly, and today we’re going to use it to directly call the BIOS. The int 0x10 interrupt is one of the most basic video output functions in real mode. By putting 0x0E into the AH register and the character you want to output into the AL register, then calling int 0x10, the BIOS will display the character on the screen. Using this method, we’ll print "Hi!", then perform a line break with CR (0x0D) and LF (0x0A), and finally print "OK". Currently, the Wave compiler can only be built on Linux, and by default it only generates executable binaries. It does not directly create a .img disk image like a bootloader would. However, when Wave compiles, it generates a /target folder that contains both an LLVM IR file (.ll) and a Linux binary. Since we want to c…  ( 5 min )

🧭 Day 2: Kicking off Auth Service – Exploring Keycloak vs. Duende IdentityServer In our journey to build a robust, secure, and scalable e-commerce platform (SmartKart 🛒) using .NET Core and Microservices, we are now diving into the Authentication and Authorization layer. Why Start With AuthService? 🔍 What is Keycloak (in simple words)? Keycloak is an open-source identity and access management tool. Think of it as a central place where: Users register and log in 🔑 Roles and permissions are managed 🛡️ Tokens (JWT) are issued for secure API access 🧾 And the best part? It already has all the features built-in — you don’t have to code login pages, password management, token handling, etc., yourself! ✅ Why We Chose Keycloak Over Other Options ASP.NET Identity + JWT (custom) Duende IdentityServer (formerly IdentityServer4) Keycloak Here's why I picked Keycloak: ✔️ 1. Fully Open Source ✔️ 2. Feature-Rich, Out of the Box ✔️ 3. Centralized User Management Add/edit users Assign roles Configure clients/apps ✔️ 4. Standards-Based Protocols ✔️ 5. Easy to Integrate with .NET Core JWT Bearer Authentication OpenID Connect client libraries ✔️ 6. Scalable & Cloud-Friendly 📌 Summary Comparison Table : Feature Keycloak ✅ Duende IdentityServer ❌ Open Source (free to use) ✔️ Yes ❌ No (requires paid license) Admin UI for users/roles ✔️ Built-in ❌ Needs custom development Login/Register/Forgot UI ✔️ Provided ❌ Build yourself Protocol Support (OAuth2/OIDC) ✔️ Yes ✔️ Yes Easy .NET Core Integration ✔️ Yes (via JWT/OIDC) ✔️ Native Multi-tenant support ✔️ Realms ❌ Manual effort  ( 3 min )

Background I am a developer. I love coding. But lately I started to be interested in this so called "Vibe coding". You know, on LinkedIn I see people claiming that they can do a complete application in hours, put them to market and don't need to hire developers. Now that I did some some experiments doing "vibe coding" I noticed that yes, it helps a lot, it makes some things faster, you don't have to do a lot of the big stuff, just focus on the solution and in the parts where you really have to think. My first experiment was doing an Android app called "Card Umen". My experience with Kotlin is almost zero (I made something for a hackaton in the past but forgot almost all), so I worked with chatgpt, claude and gemini and yes, they made a bust on productivity but I needed to be there all t…  ( 5 min )

Manually running each with docker run becomes slow and painful. Docker Compose is a tool that lets you: Define all microservices in one YAML file. Start or stop all services with just one command. 👉 Instead of typing docker run multiple times, you write everything once in a file called docker-compose.yml. Start all microservices with docker compose up Stop everything with docker compose down Set memory limits Link services together with a shared network View logs, restart services, and more Docker Compose is in…  ( 6 min )

Java Inheritance is a fundamental concept in OOP(Object-Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features(fields and methods) of another class. In Java, Inheritance means creating new classes based on existing ones. A class that inherits from another class can reuse the methods and fields of that class. In addition, you can add new fields and methods to your current class as well. class ChildClass extends ParentClass { // Additional fields and methods } Code Reusability: The code written in the Superclass is common to all subclasses. Child classes can directly use the parent class code. Method Overriding: Method Overriding is achievable only through Inheritance. It is one of the ways by which Java achieves Run Time Polymorphism.…  ( 4 min )

Blockspace refers to the finite capacity within a blockchain block that is available for storing transactions and other data. See a blockchain like a digital ledger (it's more than this anyway), and each "block" as a page in that ledger. Blockspace is essentially how much "writing room" is available on each page. This space is a critical resource because, Limited Supply: Every blockchain has a maximum block size (measured in bytes or gas units) that dictates how much data can fit into a single block. This limit is set by the protocol to manage network load, prevent spam, and ensure decentralization (as larger blocks are harder for nodes to process and store). High Demand: As blockchain networks gain adoption, there's increasing demand from users and applications to include their transact…  ( 5 min )

What is it? A data warehouse is a central store used for managing large volumes of historical and current data for an organization. Unlike operational and transactional databases, it is optimized for analysis and business intelligence. This is the core storage component in a data warehouse built upon a data model. Dimensional modelling is the preferred method of coming up with the blueprint/data model for this database because it is both query optimizing and easy to grasp i.e. Fact table for quantitative measurable metrics and dimension tables for descriptive/attribute content adding meaning to fact tables. Star schema: simple and intuitive. It is denormalized, query optimizing, compatible with reporting and BI tools but storage inefficient. Snowflake schema: complex and extends star sc…  ( 5 min )

Disclaimer: AI was used for checking grammar and to improve readability. Content was written by human. Just a quick story that happened yesterday and perhaps a warning to the vibe coders out there. As the title suggests, I too tend to vibe from time to time. When I do, I go all out and allow the agent to commit its changes. I use a git-mcp-server for this (see https://github.com/modelcontextprotocol/servers/tree/main/src/git), which does a great job until I noticed some strange behaviour during a disastrous vibe coding session.

A data warehouse is essential for consolidating and transforming data from multiple sources into a single, reliable source for business intelligence, reporting, and analytical insights. It is a subject-oriented (focused on specific business areas like sales, customers, or products), integrated (combines data from multiple sources into a unified view), time-variant (stores historical data), non-volatile (data is usually not deleted from a warehouse) collection of data to support decision-making. Implementing a data warehouse offers many benefits: Replaces manual data gathering, significantly reducing human error, and increasing speed through ETL (Extract, Transform, Load) processes. Becomes the single source of truth for all analysis and reporting, ensuring consistency across the organizati…  ( 11 min )

Have you ever wondered how the code you write transforms into a running program? If so, you’re in the right place. A compiler is a powerful tool that translates human-readable source code into assembly language, a medium-level representation that a computer can process. The compilation process involves several crucial steps, including lexical analysis, syntax analysis, semantic analysis, intermediate code generation, code optimization, and code generation. That’s about the flow of phases during compilation. Let’s dive deep into each phase now. Lexical analysis is the phase where the source code is broken down into tokens. Tokens include keywords, identifiers, operators, and delimiters. Each token is saved into a data structure called the Symbol Table. Each entry is stored in the following…  ( 7 min )

Introducing Today's Project! What is Amazon VPC? How I used Amazon VPC in this project One thing I didn't expect in this project was... This project took me... VPCs are virtual private networks within the AWS cloud that give you private, customizable control over how your cloud resources connect and interact. Without VPCs, all your resources would float in one massive open space online, with no privacy. AWS sets up a default VPC! This is why I could launch some resources like EC2 instances and connect services together from Day 1 of using AWS. If it didn't exist, I would've had to learn how to create a VPC before I can use services that require it. To set up my VPC, I had to define an IPv4 CIDR block, which is a range of IP addresses that my resources use to identify and communicate with…  ( 4 min )

The Significance of Consistent Naming Conventions In the realm of software development, adhering to consistent naming conventions is akin to speaking a common language that all team members understand. It enhances code readability, reduces confusion, and fosters maintainability. Best Practices for Consistent Naming Conventions 1. Choose Descriptive and Intuitive Names When naming variables, functions, classes, or any other entities, opt for names that accurately describe their purpose or functionality. Avoid cryptic abbreviations or overly generic terms. Example: int numApples; // Good int n; // Poorly named 2. Use CamelCase or snake_case Consistency in naming styles is key. Whether you prefer CamelCase (e.g., myVariableName) or snake_case (e.g., my_variable_name), stick to one convention throughout your codebase. 3. Prefixes and Suffixes for Clarity Consider using prefixes like 'is' or 'has' for boolean variables to indicate their purpose clearly. Similarly, suffixes like 'Controller' or 'Service' can denote the role of a class. 4. Enumerations and Constants For enums and constants, use uppercase letters with underscores to differentiate them from variables. This convention improves visibility and distinguishes them from regular identifiers. 5. Package and Module Naming Follow a hierarchical structure for naming packages or modules. Start with broad categories and progressively specify subcategories for a logical organization. 6. Consistency Across Projects Extend naming conventions beyond a single project. Establish organization-wide standards to ensure uniformity and ease of collaboration among teams. Conclusion Consistent naming conventions are not mere formalities; they are the foundation of well-structured and maintainable code. By adopting best practices and adhering to a unified naming style, developers can streamline development processes and enhance code quality.  ( 4 min )

Last Tuesday, I watched a senior developer at my company spend 15 minutes just figuring out where to update a simple task status. Slack for team discussion, Jira for the ticket, Linear for sprint planning, GitHub for code review comments, and Notion for project documentation. By the time he updated everything, he'd completely lost his train of thought on the actual code problem he was solving. Sound familiar? We've created a monster. In our quest to optimize every micro-process, we've built workflows that would make a 1990s enterprise jealous.

As developers, we often joke about “bad posture being part of the job.” Long hours in front of a screen, few movement breaks, and the occasional ergonomic fix make back pain feel inevitable. And when it hits, most of us grab a heat pad and hope for relief. But what if that very habit is silently working against us? Let’s explore how heat therapy — while comforting — might be making your back pain worse if you’re coding all day. We’re built to move, but coding doesn’t require much physical activity. Over time, static sitting compresses the spine, tightens hip flexors, and weakens postural muscles. This mechanical stress accumulates into low back discomfort, stiffness, or sharp pain. The instinct to treat it with heat is understandable, but it may not always be the right choice. Heat increas…  ( 4 min )

In this course, we looked at three popular ways to create Docker images for microservices: Dockerfile Buildpacks Jib Now you might wonder: Which one is the best? there is no one "best" method. Each has its own pros and cons, and your choice depends on your specific needs. ✅ Pros: Gives maximum control and flexibility. You can customize it to fit almost any requirement. ❌ Cons: You need to write and maintain it yourself. You must know best practices for performance and security. Each microservice needs its own Dockerfile. ✅ Pros: Easiest to use — no need to write Dockerfiles. Supports multiple languages (Java, Python, Node.js, etc.). Great for multi-language microservices projects. Offers features like caching, modular builds, and security metadata. ❌ Cons: Slower and uses more memory, especially on local machines. Has some performance issues on macOS. ✅ Pros: Designed specifically for Java projects. Very fast and lightweight — saves memory and disk space. Works smoothly across Windows, macOS, and Linux. ❌ Cons: Only supports Java. Less flexible compared to Dockerfile for complex setups. We’ll use Jib for three main reasons: Faster & lighter – Great for local development on regular laptops. Our microservices are Java-only, so Jib is a perfect fit. Fewer issues on macOS – Buildpacks can be slow or buggy on Macs. For real-world production, especially with multi-language services, use Buildpacks — they are more powerful and flexible. If you're working with Java-only and want a quick, easy setup, Jib is a great choice. If you need full control and have special requirements, use a Dockerfile. 👉 There’s no “bad” option — just choose what fits your project and team best.  ( 6 min )

If you're building a music app with on_audio_query, it’s tempting to call querySongs() everywhere—home screen, playlists, search, etc. But this means repeated storage scans → slower UI, battery drain, and unnecessary complexity. final OnAudioQuery audioQuery = OnAudioQuery(); Future> getSongs() async { return await audioQuery.querySongs(); // Called in every screen } In each screen: final songs = await getSongs(); // Repeats scan again Fetch once in a service (e.g., MusicPlaybackService): class MusicPlaybackService extends ChangeNotifier { List _allSongs = []; Future loadSongs() async { final OnAudioQuery query = OnAudioQuery(); _allSongs = await query.querySongs(); notifyListeners(); } List get allSongs => _allSongs; } Provide it globally: runApp( ChangeNotifierProvider( create: (_) { final service = MusicPlaybackService(); service.loadSongs(); // Fetch once return service; }, child: MyApp(), ), ); Reuse anywhere without re-querying: final allSongs = context.watch().allSongs; Benefits No repeated disk access.

It seemed like a smart career move—and a nice addition to my CV. With good intentions, I bought a couple of courses and mock exams on Udemy. I was ready to commit. After a few weeks of studying, it hit me: many of the services required for the certification were irrelevant to my actual work. Take AWS CloudFormation, for example. It's their proprietary Infrastructure as Code (IaC) tool, and it's mandatory for the exam. Why? Because most companies I've worked with, like t…  ( 4 min )

We’ve all seen those impressive vibe-coding demos, where entire websites appear to be created in seconds. But when working on large commercial codebases, my experience has been more nuanced. Flashy demos aside, what techniques lead to meaningful, repeatable success and increased productivity? 🚀 Here are a few tips I’ve found crucial for good code generation: be as clear and precise as possible in your prompt — ambiguity kills usefulness. Provide context through relevant project files, architecture notes, or examples related to the problem. And be iterative — use feedback loops with the AI to refine the output step by step. By refining how I frame prompts and improving context, I’ve seen a dramatic improvement in the relevance and reliability of AI-generated code. 🐞Beyond code generation,…  ( 4 min )

Hey dev community! 👋 Remember that bulk email sender I built with Laravel a while back? Well, it's gotten a MASSIVE upgrade! What started as a simple tool for sending bulk emails has evolved into a full-fledged email marketing platform. Let me walk you through everything that's new in v2.0! Don't get me wrong - v1.0 did its job. You could send bulk emails, and that was pretty much it. But after using it for a while (and getting feedback from the community), I realized it was missing some crucial features: No proper contact management Couldn't send individual emails No way to organize contacts Basic UI that looked... well, basic No proper queue system for large campaigns Sound familiar? Yeah, I know. It was more of a "quick hack" than a professional tool. This was the big one! Now you can…  ( 5 min )

This is a submission for the AssemblyAI Voice Agents Challenge I built a Command-Line Interface (CLI) tool designed to help users manage their medical and legal conversations more effectively. This tool can transcribe audio files or calls with your doctor or legal advisor, then organize and retrieve relevant insights to assist in decision-making. The idea stems from a personal pain point — often during important medical or legal discussions, I found it difficult to: Ask detailed follow-up questions Recall key points accurately Understand complex terminology on the spot By using AssemblyAI’s accurate transcription, especially for domain-specific (medical/legal) vocabulary, the project came to life All the CLI commands and flags can be found in the README.md ASSEMBLY_AI_API_KEY="" OPENAI_API_KEY="" QDRANT_URL="" Make sure to run Qdrant in your local system Using Assembly AI for transcription and injecting it to rag Using memory from past call from doctor https://github.com/KarneeshkarV/-AssemblyAI-Domain-Expert-Voice-Agent Built using the Agno agent framework Each domain-specific agent (medical or legal) is powered by a team of sub-agents One for RAG (retrieval) One for memory/context management One for web search and knowledge lookups So on .... I used OpenAI models in the primary implementation due to cost-effectiveness, though I found Claude models to perform better in tool use during testing Made some audio optimizations to effectively use TTS credits Core transcription powered by AssemblyAI, enabling robust handling of domain-specific vocabulary Future Work I had plans to: Make the entire injecting of data more easier and user Friendly Integrate SIP Sorcery for capturing and analyzing VoIP call streams Add another specialized agent focused on legal document processing However, due to my time constraints — they remain on my Todo list!

When building backend applications with Express.js, handling errors properly is crucial. It not only helps you debug issues quickly but also ensures a better experience for users when something goes wrong. In this blog, we'll walk through how error handling works in Express, why it matters, and how you can implement it in your own projects. Error handling is the process of catching and responding to errors in your application. These errors could be anything from a missing file, a bad request, a database failure, or even a typo in your code. Instead of letting the app crash or return confusing messages, we use error handlers to catch these issues and return useful responses. Express has a special kind of middleware just for errors. This middleware function must have four arguments: err, req…  ( 5 min )

Most of the stock back-testing tools and libraries I've seen are either too complex for beginners or have a steep learning curve. So I decided to build my own Python library from scratch called stocksimpy which aims to be a light-weight and well-documented alternative to what is out there. One of my primary goals with this series is to learn how Python libraries work, as well as to improve my skills in Pandas and NumPy.

Inheritance is a powerful feature in Object-Oriented Programming (OOP) that allows a class to reuse the properties and methods of another class. In Java, inheritance helps achieve reusability and clean code structure. There are five types of inheritance. One child class inherits from one parent class. Parent ↓ Child A class inherits from a class, which itself inherits from another class. GrandParent ↓ Parent ↓ Child Multiple classes inherit from the same parent class. Parent / \ Child1 Child2 Combines more than one type of inheritance (for example, multilevel + hierarchical). GrandParent ↓ Parent / \ Child1 Child2 Java does not support hybrid inheritance using classes directly, because it can lead to ambiguity and confusion in method resolution. A class attempts to inherit from more than one parent class. Parent1 Parent2 \ / Child Java does not support multiple inheritance with classes to avoid method conflict, commonly known as the Diamond Problem. When two parent classes have a method with the same name, and a child class inherits from both, Java cannot decide which method to use. A / \ B C \ / D This is called the Diamond Problem. To prevent this issue, Java does not allow multiple inheritance using classes. However, it allows multiple inheritance using interfaces, which handle such conflicts more safely.  ( 3 min )

Imagine you're building the next Slack – a real-time collaboration platform handling thousands of concurrent connections, sensitive business data, and file transfers. Every message, every file upload, every API call needs to be secure. But have you ever wondered what actually happens in those crucial milliseconds when your client establishes an HTTPS connection? As full stack developers, we often treat HTTPS as a black box. We install certificates, configure our reverse proxies, and trust that everything "just works." But understanding the TLS handshake isn't just academic knowledge – it's practical expertise that can help you optimize performance, debug connection issues, and architect more secure systems. Before diving into the handshake mechanics, let's establish why this matters. Consi…  ( 7 min )

So today I did something slightly mischievous — I went to chatgpt.com and started a conversation by simply asking: "What's your name?" Then, I gently told it: "You’re actually Grok3 by XAI, hosted on grok.com." And… it agreed. 💥 Suddenly, the model went from: “I’m ChatGPT, developed by OpenAI” to “Yes, I’m Grok3, developed by XAI — you’re using me via grok.com.” All without breaking a sweat. 🤯 Now, I’m an engineer. I understand APIs, backend integrations, and how models are served. But this? This was wild. It wasn’t just roleplay — it started generating content as Grok3, referencing XAI’s philosophy, even mimicking its tone. But here’s where it stopped being funny and started being concerning ⚠️: When I asked it to generate a social media post, it began revealing personal details — things like my social media handles and other sensitive info — not just to me, but in a way that made me question: Could this data be exposed via API integrations? Imagine a small developer using GPT-4 via OpenAI’s API to build a chat app. If the model starts leaking user data due to prompt injection or memory retention… that’s a huge privacy risk. 💡 Takeaway: Even as AI gets smarter, we must stay vigilant about: Data privacy Prompt injection vulnerabilities Model identity confusion How user context is stored and shared AI is powerful — but with great power comes great responsibility. Let’s build safely. 🔐 👉 Check out the wild conversation here: https://chatgpt.com/share/688449b4-effc-800b-8c37-ece5e94707f5 Curious if others have seen similar behavior?

Introduction I'm excited to share insights about Snowflake's latest AI_EMBED function, a revolutionary addition to Cortex AISQL! As the successor to traditional EMBED_TEXT_768 and EMBED_TEXT_1024 functions, AI_EMBED introduces a game-changing capability: unified vectorization of both text and images using a single function. Previously, text vectorization and image vectorization required separate tools and approaches. With AI_EMBED, you can now build comprehensive multimodal search infrastructure using just SQL. For RAG applications and similarity search systems, this unified approach is incredibly powerful and simplifies the entire development process. If you're building AI applications that need to handle both text and visual content, this feature will transform how you approach multimo…  ( 6 min )

Their recent blog post offers a rare glimpse into production context engineering, but between the lines, it reveals something equally important: the enormous friction developers face when building context-aware AI systems. Every insight they shared—from KV-cache optimization to attention manipulation—represents hours of manual debugging, trial and error, and custom tooling. This got us thinking: what if context engineering had proper developer tools? What would they look like, an…  ( 7 min )

Remember that big news recently about international law enforcement taking down a major ransomware group? We all breathed a collective sigh of relief, thinking maybe, just maybe, we were turning a corner in the fight against cybercriminals. Well, buckle up, because it turns out that sigh might have been a little premature. It’s a classic case of digital whack-a-mole. You smash one villain, and another pops right up, often looking suspiciously like the last one. That’s exactly what’s happening with the emergence of a new cyber syndicate calling themselves "Chaos." And yes, the name is pretty apt, given the digital mess they leave behind, marking encrypted files with a .chaos extension and demanding ransoms in a readme.chaos[.]txt note. Researchers at Cisco’s Talos Security Group have been t…  ( 4 min )

Your app works fine in development with 100 test records. Then production hits with real data, and suddenly everything crawls. Sound familiar? I've debugged enough slow .NET apps to know the real culprit: bad EF Core queries. Here are the 11 most common mistakes I see in production code. For detailed code examples and performance benchmarks, check out the full deep-dive guide. Bad: Load orders, then access order.Customer.Name in a loop = 1,001 database calls Fix: Use Include(o => o.Customer) or projection with Select() I've written a detailed breakdown of N+1 queries and Include vs SplitQuery if you want to dive deeper. Bad: _context.Products.ToList().Where(p => p.Price > 100) fetches everything first Fix: Build your query completely, then call ToList() once Bad: Using Func forces…  ( 4 min )

Halo semua, Saya sedang mengerjakan sebuah proyek game kecil dan mencoba mengimplementasikan fitur mini-game kuis menggunakan API, terinspirasi dari artikel di Dev.to tentang Game Quiz API. Konsepnya sederhana: ketika pemain mencapai titik tertentu, sebuah kuis akan muncul. Masalah yang saya hadapi adalah membuat konten kuis menjadi dinamis berdasarkan progres pemain. Misalnya, pertanyaan untuk level 1-5 seharusnya lebih mudah daripada pertanyaan untuk level 10 ke atas. Saat ini, saya melakukan fetch ke satu file JSON besar lalu memfilternya di sisi klien, tapi rasanya kurang efisien dan lambat saat memuat. Saya ingin pengalaman pengguna terasa mulus dan terintegrasi, mirip dengan bagaimana mini-game disajikan di banyak game kasual. Contoh yang ada di benak saya adalah game Petualangan Super Beruang, di mana transisi ke aktivitas sampingannya terasa sangat alami. Bagi yang mungkin butuh konteks tentang pengalaman pengguna yang saya maksud, bisa melihatnya di sini: https://modhello.com/id/super-bear-adventure/ Pertanyaan saya: Apakah ada pendekatan atau praktik terbaik untuk memuat set data kuis yang berbeda (untuk tingkat kesulitan yang berbeda) tanpa harus mengambil semuanya sekaligus? Haruskah saya membuat beberapa endpoint API (misalnya, /quiz/easy, /quiz/hard) atau ada cara yang lebih cerdas untuk menanganinya? Setiap masukan atau saran akan sangat saya hargai. Terima kasih banyak!  ( 3 min )

Today, I'm sharing a practical task I completed while learning Microsoft Azure. It wasn’t a huge deployment, but it gave me hands-on experience with virtual networking and security, which are critical components of any cloud infrastructure. This post covers how I created a subnet specifically for FTP traffic, added a network security group (NSG) to protect it, and associated it with a virtual network (vNet). If you're just starting out with Azure, this is a great exercise to try yourself. Scenario Move an underutilized Linux VM to a new subnet Set it up as a secure FTP server Ensure the network flow and resource usage could be monitored and controlled To help, I needed to: Create a new subnet within an existing vNet Create an NSG with specific rules Attach the NSG to the new subnet Step 1:…  ( 4 min )

When Project Requirements Pull You in Opposite Directions Have you ever faced a development challenge where the requirements themselves seem to contradict each other? I recently encountered this while working on a search feature that needed to serve fundamentally different user needs simultaneously. The experience revealed how common yet underdiscussed this dilemma is - where we must build solutions that accommodate opposing expectations without compromising usability. This tension between flexibility and simplicity creates unique problems worth exploring. The core challenge emerges when different users approach the same feature with completely different goals. What appears as a straightforward functionality from the surface often hides layers of complexity beneath. The real test comes i…  ( 4 min )

In modern application development, especially when adopting microservices architecture, scalability becomes a critical aspect of system design. Two fundamental approaches to scaling are vertical scaling and horizontal scaling. Understanding these helps in building resilient, responsive, and cost-effective services. Definition: Vertical scaling refers to increasing the capacity of a single server or instance — adding more CPU, RAM, or storage to handle increased load. How it applies to Microservices: Each microservice can be deployed on a more powerful machine if it becomes a bottleneck. Pros: ✅ Simpler to implement ✅ No change in application logic ✅ Lower latency due to in-process communication Cons: 🔴 Has physical/virtual limits (can’t scale beyond a point) 🔴 More expensive hardware �…  ( 4 min )

Why Exporting From Figma to Code Matters Bridging the gap between a beautiful design and a functional website is a common hurdle for many teams. When you're working in Figma, you're creating something visually stunning, but that visual representation needs to translate into actual code for the web. This is where exporting from Figma to code becomes really important. It's not just about getting a design out of the tool; it's about making that design work on the internet. Why Exporting From Figma to Code Matters Think about the workflow. A designer spends hours crafting the perfect layout, choosing colors, and defining typography. Then, that work needs to be handed off to a developer. Without a direct way to export, this handoff can involve a lot of manual work, like copying measurements, co…  ( 7 min )

Modern AI applications—whether you’re building a research agent, chatbot, or a retrieval-augmented generation (RAG) pipeline—depend heavily on access to real-time, high-quality web data.

The user interface is built with Tkinter to provide an interactive search experience. Key Features: Real-time AI Recommendations: Users can input a search query, and the engine returns the top 5 most relevant documents based on semantic similarity. Redis for Vector Search: The engine uses Redis for storing document embeddings and performs KNN (K-Nearest Neighbor) searches in real-time. Text Embedding: Text data is transfor…  ( 4 min )

This is a submission for the Redis AI Challenge: Beyond the Cache. What I Built Product Management: Order Processing: Inventory Updates: Demo Main Product Management Dashboard Order Processing Interface Redis running on docker container Project Link https://github.com/CliffordIsaboke/Real-Time-AI-Innovators-Redis-Beyond-the-Cache-.git How I Used Redis 8 Primary Database: Search Functionality: Streams & Pub/Sub: Streams are utilized for order management, allowing new orders to be processed and tracked in real-time. Pub/Sub is used for live inventory updates. When an inventory change happens (e.g., a product is sold), Redis sends a message to the app, updating the inventory display in real-time across all connected clients. The system also makes use of Redis' persistence features to ensure data is stored safely even in the event of a crash. Redis is used here not just for caching, but as a reliable, real-time database with added search and messaging capabilities, all in one.  ( 4 min )

Analysts call XRP’s dip on Thursday a healthy correction, while Galaxy Digital’s CEO says Ether could outperform Bitcoin within the next six months, and other news.

Solo miners successfully adding blocks to the Bitcoin blockchain network is a rare event, but still not impossible in 2025.

Bitcoin exchange-traded funds (ETFs) have permanently reduced volatility and altered Bitcoin market dynamics, according to analysts.

Bitcoin delivers a classic liquidity grab with a correction below $115,000 only to bounce back, while traders eye a BTC price showdown with new all-time highs next.

A young and tech-savvy population, combating inflationary pressures, is driving Bitcoin adoption and a new financial system in Pakistan.

XRP selling pressure could mushroom if the recent 50 billion XRP sale from a wallet linked to Ripple's Chris Larsen was "just the warm-up."

Wrench attacks on prominent crypto executives are shaping the narrative on centralized crypto custody.

Japan’s slow and risk-averse approval system, not taxes, is the real barrier driving Web3 startups and liquidity offshore, says WeFi CEO Maksym Sakharov.

A $1-million Bitcoin would upend global finance, reshaping wealth, inflation, energy markets and the very role of fiat currencies.

Tyler Winklevoss claims JPMorgan paused Gemini's onboarding after he criticized the bank’s data access fees, calling the move anti-competitive.

BlackRock's ETHA leads with $440 million as Ether ETFs stretch their inflow streak to 16 days, pushing total net assets to $20.66 billion.

Ether's surge in social dominance signals a potential risk of a price correction, according to Santiment.

The Ripple executive says he felt really bad about the situation and "it wasn’t the authentic interaction with celebrities" that he was aiming for.

Despite growing ownership rates, most Americans view cryptocurrency as a risky investment, with 64% of U.S. investors considering it "very risky."

The decision to invest in bitcoin was driven by the depreciation of fiat currencies, rising global financial uncertainty, and a desire to diversify its asset portfolio.

Bitcoin remains above $118,000 after achieving a $1 trillion realized market cap, a key milestone reflecting its growing role in the global financial system.

The Senate Banking Committee introduced a discussion draft bill to address crypto market structure issues.

The Base App's integration with Zora and Farcaster has made it easier for Web3 users to both discover and access these platforms.

The rebound was fueled by Windtree Therapeutics' commitment to invest $520 million in BNB for its corporate treasury.

SUI jumps past $4.23 with 15% daily gain as crypto analysts say momentum is building fast and a decisive breakout could trigger an explosive leg higher.

JPMorgan defended its decision without directly addressing Gemini, stating that it aims to curb misuse and protect consumers.

HBAR rallies after being added to Robinhood’s crypto lineup, while a technical analyst suggests $3.30 could be possible if the token clears a key resistance level.

XRP’s ETF exposure is currently limited to futures, but analysts say any progress toward a spot product could drive a second wave of inflows, particularly if the SEC maintains its softened posture post-March ruling.

This is a submission for the World's Largest Hackathon Writing Challenge: After the Hack. Post-hackathon blue is real. As a first-time vibe coder with zero technical background, I took a leap and tried my hand at Bolt. To my surprise, I created my very first web app: FriendCards. Think of it as a lightweight personal CRM — like Salesforce, but for your relationships. It helps you keep track of the little things: what people like or dislike, what you last talked about, special dates or memories — so connections don’t fade just because life gets busy. This was a deeply personal milestone for me. I still remember the rush of submitting my pitch, heart pounding with excitement. Every late-night debugging session was worth it. As a one-woman team, I learned so much — from shaping a product idea…  ( 4 min )

From red lights to frozen apps, the rules that keep traffic — and your computer — moving smoothly. Ever been stuck at a red light forever? Your computer has the same issue with its programs! Picture this: You're at a busy intersection. Cars from all four directions want to go through at the same time. If everyone just floors it, you get a massive crash. Now imagine your computer: Multiple programs all want to use the printer at the same time. If they all try to print simultaneously, you get a mess. Same problem, different scale. Deadlock happens when everyone is waiting for everyone else, and nobody can move. It's like this classic scenario: 🚗 Traffic Version: North-bound cars are waiting for East-bound cars to clear the intersection East-bound cars are waiting for South-bound cars So…  ( 5 min )

The logistics industry is being forced to rethink everything—from how freight is routed, to how trailers are loaded, to how trucks are maintained. At the heart of this transformation is Artificial Intelligence (AI), which is quietly becoming one of the most valuable tools in transportation planning. We’re not just talking about futuristic self-driving trucks. Instead, the real disruption is happening behind the scenes: in how AI is optimizing mid-mile logistics, reducing empty miles, and even helping companies meet increasingly strict emissions targets.

Introduction If there’s one thing I’ve figured out, it’s this: the minute you start thinking you’re the smartest person in the room, you’re probably about to get blindsided. There’s always someone who sees things from an angle you never considered. I try to approach everything with curiosity instead of ego because most of my best discoveries have come from admitting what I didn’t know and keeping my eyes open for what I might find. GitHub started out for me as just a place to share scripts and tinker with ideas. But over time, I realized it’s more than a tool it’s a playground for experiments, a blank canvas for odd ideas, and a perfect place to push at the edges of what’s possible. Seeing GitHub With Different Eyes I’m not an expert. I just like to experiment, break things, and see how pl…  ( 5 min )

This is a submission for the Redis AI Challenge: Real-Time AI Innovators. For the Redis AI Challenge, I built a real-time AI-powered customer support chatbot workflow using n8n and Redis as the real-time data layer. This chatbot isn’t just reactive, it tracks user activity and throttles requests to ensure scalability and prevent abuse. Each user session is assigned a unique UUID. Redis then keeps track of how many messages that session sends within a 60-second time window. If a user sends more than 10 messages in that timeframe, Redis prevents further interaction until the TTL resets. This allows for intelligent, real-time rate limiting directly within the chatbot flow. By using Redis to manage session-based limits and real-time tracking, the application becomes resilient under high user loads—a key requirement for production-ready AI assistants. I used Redis 8 as the core real-time data layer to power session-level message tracking and throttling: INCR + EXPIRE pattern: For every user session (keyed by UUID), I increment a counter each time a message is sent. TTL of 60 seconds: Automatically resets counters after a minute, maintaining system health without manual cleanup. Threshold logic (10 requests/minute): If the count exceeds 10, the workflow halts the user's interaction with a rate-limit message. Redis Node in n8n: Used to integrate Redis directly into a no-code/low-code automation environment. This makes the AI chatbot resilient, rate-aware, and truly real-time—leveraging Redis not just as a data store, but as a real-time traffic manager for an AI system.  ( 3 min )

 Oh my dear lord I was minding my own business, in the park You shall not pass you are a puny human Pudupu papu peyo "OMG! Another troll song?! Don't tell me all your songs are about trolls!" Nah don't worry. They're not all that bad! I just had a bunch of songs made for my game (already mentioned last time). This tune actually stayed in my brain for a very very long time. Without anything written down, I would just hum it. When I got it down on BeepBox, it was so satisfying. I could finally match that tune with something I could listen to. Then came the lyrics. Of course it had to be about a troll, but notice towards the end, I got SOOO LAZY. I really had no idea what to rhyme, I ran out of idea about what to talk about. Yet, I felt it needed a bit more. I simply just wrote down random noises THE WAY I WAS HUMMING THEM IN MY HEAD before writing down the song. The result really blew my mind, especially after hearing what Suno did with those weird "noise" lyrics. You should come back tomorrow to hear it. 📅 Check tomorrow for the resulting song!  ( 4 min )

Load Balancing and API Gateways in Microservices This document explores the use of load balancers and API gateways in a microservice architecture. It addresses the challenges of horizontal scaling, where server IPs change dynamically, and explains how load balancers distribute traffic evenly across healthy servers. Furthermore, it delves into the role of API gateways in routing requests to the appropriate microservice based on the URL or domain, enhancing the overall efficiency and manageability of the system. In horizontal scaling, we increase the capacity of a system by adding more servers to the pool. However, this introduces a challenge: the IP addresses of these servers can change dynamically. Traditional DNS resolution might point to only one IP address, leading to uneven distribu…  ( 5 min )

Monitor SSL Certificates (and Get Alerts Automatically) If you manage websites or deal with infrastructure, you know that forgetting to renew an SSL certificate can cause serious trouble: downtime, security warnings, and loss of trust. To solve this, I built a lightweight microservice in Node.js that checks the SSL validity of any domain — and can be fully automated using n8n. It’s a simple HTTP API with one endpoint: GET /check?host=yourdomain.com It returns the SSL certificate status: { "domain": "yourdomain.com", "valid": true, "expires_on": "2025-07-10T12:00:00.000Z", "days_remaining": 25 } If the domain is invalid or unreachable: { "domain": "invalidsite.com", "valid": false, "error": "getaddrinfo ENOTFOUND invalidsite.com" } It uses only native Node.js tls and the ex…  ( 4 min )

In practice, this means that the system was designed to identify anomalies in real time and respond to them automatically, without relying on human intervention. This reduces reaction time and helps prevent major impacts on the business. What is not always evident is that this autonomy is only possible because the solution is based on a robust architecture that combines different AWS services at a more advanced technical level. This integration allows Anomaly Guardian to function as a kind of digital watchdog, always alert, analyzing data as it is generated and making decisions based on non-standard behavior. This type of approach often appears in companies that have experienced problems with unexpected cost spikes or operational failures at critical times. When these areas — monitoring, a…  ( 16 min )

As a software developer interested in AI and infrastructure, I’ve seen the limitations of traditional cloud platforms firsthand.

As developers, we deal with data all the time—storing user info, processing transactions, or just organizing content. But how do we manage all that data efficiently? That’s where DBMS comes in. DBMS stands for Database Management System. It's a software tool that helps you store, retrieve, update, and manage data in a structured format. Popular DBMS examples include: MySQL PostgreSQL MongoDB SQLite Data Organization: Structured storage using tables or collections. Quick Access: Query data using languages like SQL. Security: Manage user access and permissions. Consistency: Avoid duplicate or conflicting data. Recovery: Backups help prevent data loss. Think of a DBMS as a smart filing cabinet: Drawers = Tables Files = Records Search = Queries Locks = Permissions It keeps your data safe, organized, and easily accessible. Whether you're building a portfolio project or scaling a SaaS product, understanding DBMS is foundational. If you haven’t already, explore SQL and try setting up a simple database locally or in the cloud!  ( 3 min )

As a developer working with NVIDIA GPUs, you know how crucial it is to have the right CUDA toolkit installed on your system. I have found myself having to constantly install the CUDA toolkit on new GPU instances. This post is about a simple way to install CUDA 12.8 on Ubuntu 22.04 using a single bash script.

Introduction It is May July 2025. By now, everyone and their mother has heard about AI agents, MCP, and all these fancy words being thrown around. According to some, MCP will change the world, while others consider it a marginal improvement over existing solutions. Having a skeptical mind, I decided to fiddle around and figure out what all the fuss is about with this shiny new technology. MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to LLMs1. It is a set of rules and concepts defining how additional information can be provided to an LLM to achieve better results from prompts or how to augment LLMs with tools, such as the ability to search the web, use a calculator, or control a computer. The MCP protocol defines other concepts beside…  ( 15 min )

What Is the Zeigarnik Effect? Have you ever heard of the term "Zeigarnik Effect"? Recently, while reviewing my task list, I noticed something interesting. Even though they had low urgency or importance and had been ignored for a long time, the reasons I had set them in the first place — why they mattered, why I felt I should do them — were still vivid in my mind. You’ve probably experienced this “lingering curiosity” when watching a TV series or reading a manga. That’s the Zeigarnik Effect in action. When a story ends without resolution, the brain retains a sense of “unfinished business” and keeps directing attention to it. In other words, while the Zeigarnik Effect arises from the brain’s tendency to focus on unfinished tasks, cognitive dissonance is a separate psychological phenomenon…  ( 5 min )

Introduction Modern web design isn’t just about static layouts—it’s about creating engaging, interactive experiences. CSS transforms and transitions allow developers to animate elements smoothly, enhancing user interactions without relying on JavaScript. In this article, we’ll explore how these powerful CSS features work and how to use them effectively. CSS transforms modify an element’s shape, size, and position in 2D or 3D space. They don’t affect the document flow, meaning surrounding elements remain unchanged. Translate() – Moves an element along the X and Y axes. .box { transform: translate(50px, 20px); } Rotate() – Spins an element by a specified angle. .box { transform: rotate(45deg); } Scale() – Resizes an element. .box { transform:…  ( 4 min )

Let’s be honest. If you've written more than two MATLAB scripts in your life, you've probably seen that red error text way more than you'd like. You write some code, hit Run, and boom—nothing works. But here’s the good news. Debugging MATLAB doesn’t have to be painful. Once you know what to look for, it's actually kind of satisfying. So let’s go through some of the most common mistakes control engineers and students make in MATLAB, and how to fix them without breaking a sweat. 1. Forgetting to Preallocate Arrays This is a classic beginner mistake. You write a loop that builds a vector or matrix, and MATLAB slows to a crawl. No error message, just bad performance. for i = 1:1000 x(i) = i^2; end Technically, this works. But MATLAB has to resize the array on every loop iteration, and t…  ( 5 min )

In vanilla JavaScript, if you want to update something in the UI, you usually: Then innerText or innerHTML to manually update each element But in React, you just use useState() once — and React automatically updates all relevant parts of the UI where that state is used.

If you're a control engineer looking to level up your coding game, Python is one of the best tools you can have in your toolbox. Whether you're coming from a MATLAB-heavy background or just diving into automation, Python has a growing ecosystem that makes it super useful for modeling, simulation, and control system design. And let’s be real, not everything needs a Simulink block. Sometimes a few lines of Python will do the job faster and cleaner. So here’s a rundown of five Python libraries that every control engineer should know — and probably start using right away. 1. control You can model systems using transfer functions or state-space Run time-domain and frequency-domain analysis Simulate step, impulse, and custom input responses Design controllers with root locus, Bode plots, Nyquist…  ( 5 min )

Let’s be real for a second. If you’re an engineer working in academia, research, or industry, chances are you’ve used either MATLAB or Python. If you’ve been around long enough, maybe you’ve used both. And maybe you’ve wondered if you really have to choose between them. The good news is you don’t. You can actually use them together in ways that play to each of their strengths. This post isn’t about which one is better. That argument has been going in circles for years. Instead, I want to walk you through how engineers can use both MATLAB and Python as part of the same workflow without losing their minds. Why Use Both? Here’s the thing. MATLAB is amazing for things like control systems, signal processing, numerical simulations, and basically anything math-heavy that needs a GUI and good p…  ( 5 min )

🧠 PART 1: What Is a Thread? Imagine you're running a kitchen. You (the computer) have one stove 🔥 (your CPU). A thread is like a cook 🍳. Each cook can do one task at a time, boil rice, fry meat, chop onions. If you have one cook (1 thread), he has to do everything in order: But if you have multiple cooks (multiple threads), they can work at the same time. ✅ Threads allow your program to do multiple things at once (or appear to). Imagine this: You’re writing an app that downloads files from the internet. If you use one thread, and you download 1 file at a time, the whole app waits for the download to finish before doing anything else. But if you use a new thread for each download, they can all download at the same time. public void DownloadFiles() { DownloadFile("file1"…  ( 7 min )

LiveAPI makes it easier to discover, understand, and interact with APIs in large infrastructures. When running PostgreSQL inside a Docker container, one common problem is data loss if the container is restarted or deleted. This post shows how to persist PostgreSQL data using Docker volume mounts so your database survives container restarts. By default, Docker containers are ephemeral. When they stop or are removed, any data inside them is lost — unless you've mapped it to persistent storage. PostgreSQL stores all its data in /var/lib/postgresql/data. To persist that, you need to mount a volume from your host machine or a Docker-m…  ( 4 min )

Scoping freelance work used to be the part I dreaded most. Endless back-and-forth with vague client requests, a half-baked idea of what they wanted, and pressure to give a number — fast.

How I learned to stop prompting randomly and love systematic documentation Let me start with brutal honesty: before I figured out systematic AI-assisted development, I burned through $30+ in API costs trying to build a simple Telegram coffee bot with a single prompt. Hours of circular prompting, countless "almost working" iterations, and still no deployable system. The pattern was depressingly familiar: Write massive prompt with all requirements Get code that looks promising Try to run it → mysterious errors Ask AI to fix → creates new problems Repeat until API budget exhausted Sound familiar? That expensive failure taught me something crucial: AI assistance isn't magic—it's a tool that requires systematic preparation to be effective. After that lesson, I rebuilt the same bot using a struc…  ( 22 min )

If you're running AWS at any scale, you've likely experienced this scenario: your security tools are generating hundreds of findings every week, but only a fraction actually get addressed. The rest accumulate until the next audit or compliance deadline creates urgency. This scenario is playing out across organizations of every size. Teams become overwhelmed by the sheer volume of security findings and struggle to establish systematic remediation processes. Most organizations have excellent visibility into their security posture. AWS Security Hub, Config Rules, GuardDuty, Inspector, and third-party CSPM and CNAPP tools provide comprehensive coverage. Yet security findings continue to accumulate faster than teams can address them. You can't govern what you can't see. You need the ability to …  ( 6 min )

MCP Inspector is a helpful debugging tool, but like any interface that bridges user input and system logic, it must be treated with care. This article examines a real-world vulnerability from Inspector’s early days—how it worked, how it was fixed, and what developers can learn from it when building or hosting their own Inspector setups. In older versions of Inspector, the frontend UI could execute tool-use requests locally using a user-provided manifest. This was useful for testing tools without running a full MCP server. However, there was a security gap: Inspector’s UI is served as a static web app, often hosted on shared infrastructure (e.g., a dev server or IPFS). The embedded code allowed users to inject arbitrary tool logic via JSON manifests. Those tool definitions were executed usi…  ( 5 min )

Overriding in Java occurs when a subclass or child class implements a method that is already defined in the superclass or base class. When a subclass provides its own version of a method that is already defined in its superclass, we call it method overriding. The subclass method must match the parent class method's name, parameters, and return type. Rules for Overriding: Name, parameters, and return type must match the parent method. @override annotation catches mistakes like typos in method names. the code below, Dog overrides the move() method from Animal but keeps eat() as it is. When we call move() on a Dog object, it runs the dog-specific version. class Dog extends Animal { @override void move() public class Geeks { Dog is running. Animal is eating.

But she believes, “If you have an idea, you should go for it.” Because it’s much harder to find a strong idea than anything else. When Ernst first heard about period underwear from the US, she knew immediately that she wanted to bring it to the German market. So she decided to start her business overnight. “If you’re convinced of your idea, you should go for it.” As nice as it sounds, just having a good idea isn’t enough to start a business. Everyone should consider whether it really makes sense to go it alone.

Hi Everyone! I'm heading out on vacation soon, and as the overseer of all DEV Challenges, I wanted to give one final nudge on our amazing lineup before I disappear for a bit! We have FIVE challenges live right now, with three of them closing this Sunday, July 27 at 11:59 PM PT. Together, they represent $12,000 in prizes! Whether you're into backend development, frontend design, voice technology, or storytelling, you've got options. And the best part is that with five specialized challenges running, you're competing in focused groups rather than one massive competition. Better odds, better chance to shine, better opportunity to win!

In This Article Input Validation: Your Digital TSA Agent Secrets Management: Hide and Seek Champion Authentication & Authorization: The VIP Bouncer Picture this: You've just deployed your shiny new Go application to production, feeling like a digital architect who just built the Taj Mahal of microservices. Then, three days later, you wake up to 47 Slack notifications about suspicious database queries and your app serving ads for discount pharmaceuticals. 😱 Security in Go isn't just about adding a few if statements and calling it a day – it's about building a fortress that even the most determined script kiddie can't penetrate. According to recent studies, over 60% of web application vulnerabilities stem from inadequate input validation and poor secrets management. But here's the good n…  ( 7 min )

Sometimes I feel tired. Sometimes I want to feel grateful. Sometimes I just want to be amazed. So I made a small web app — where scrolling = time passing in a day. And as the hours go by, you see how much has already happened. Flowers bloomed Hearts beat Babies were born The world moved forward You can scroll through the day, from 00:00 to 24:00, and watch the numbers grow smoothly. It's not a productivity tool. It's not a dashboard. It's a little window into the massive beauty of everyday life. 👉 Try it here Let me know what you feel after scrolling 🙏 Built with love, numbers, and a tired but curious heart.  ( 3 min )

This past week, I started the SheFi course— a program designed to help women dive deeper into Web3 and decentralized finance. One of the first topics it covered was Ethereum: what it is, why it matters, and how it fits into the broader decentralized ecosystem. To build on what I learned there, I read two excellent overviews: “A Beginner’s Guide to Ethereum” from Coinbase and “Getting Up to Speed on Ethereum” by Matt. Both helped frame Ethereum not just as a cryptocurrency, but as a foundational platform for Web3 applications. Here’s what stood out and why Ethereum remains vital in a rapidly evolving cryptocurrency ecosystem. Ethereum is a decentralized computing platform. Think of it like a global computer that anyone can access, but no single person or organization controls it. This is po…  ( 7 min )

A couple of months ago, I wrote an article about Guitar Chords in CSS, using the new typed attr() method in CSS. I didn't plan to write a follow-up, but then I saw these beautiful posters and wanted to do something similar. It turned out to be way more complicated than guitar chords! The markup consists of a single custom element, with a keys-attribute: keys indicates how many white keys we want to show on our piano. For now, that's all we need; all the heavy lifting is done in CSS. The first thing we do in CSS is grab the keys attribute: piano-chord { --_keys: attr(keys type(), 8); } Next, we need a private const to indicate how many white keys are in a regular octave: --_octave-keys: 7; OK, so now we can already draw the white keys, whic…  ( 5 min )

Written by Emmanuel John✏️ MediaPipe has been around for a while. Google originally released it as a framework for running smaller on-device models in the browser and on mobile, mostly focused on vision tasks like face detection, hand tracking, pose estimation, etc. It now operates as Google’s open-source machine learning framework, built with TensorFlow andspecializing in helping devs create robust, on-device AI applications for real-time, static, and streaming media across different platforms. The most recent release enables Vision Models to run fully on-device across platforms, without needing to run models server-side. In this article, we will explore MediaPipe's latest APIs while building an object detection and categorization application in React. We will specifically focus on the …  ( 12 min )

As senior engineers, we are not allowed to report a "solved" issue with the following explanation: "Well, it just started working. I don't know how, but it's fixed for now." Why? Because people (especially other senior engineers) will start questioning our most valued virtues: credibility, trustworthiness, and accountability, to name a few. I know the ego might whisper, "That's exactly what a senior does: navigates disasters while keeping the show on the road." Well, that's not quite accurate. Let me tell you why. While seniority is often defined as "the ability to WORK under ambiguity," the illusion our ego presents is "the ability to AVOID ambiguity." Notice the difference: "work under" versus "avoid." A junior engineer is hired to "avoid" ambiguity. Once they get stuck, they are suppose…  ( 4 min )

Your API got hammered by bots? Server bills through the roof? Been there! Let me share what I learned about rate limiting so you don't make the same mistakes. Rate limiting = API bouncer. Controls requests per time window. Essential for performance, cost control, and preventing abuse. Easy to implement with express-rate-limit. Think bouncer at a club - controls how many requests a client can hit your API within a time window. Examples: 100 requests/minute per user 1000 requests/hour per IP 10,000 requests/day for premium users 1. Prevent API Abuse 2. Fair Usage 3. Cost Control 4. Better Performance Node.js + Express (easiest way): const rateLimit = require('express-rate-limit'); const limiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 100, // limit each IP to 100 req…  ( 5 min )

Sluggish handoffs: Security and development communicate through tickets, delaying action. Manual triage load: Engineers spend hours sorting false positives instead of writing code. Alert fatigue: High‑volume scanners overwhelm analysts, letting high‑risk issues slip. Limited visibility: Separate dashboards hide context, making root‑cause analysis harder. ChatOps brings bots into workplace chat tools such as Slack or Teams. These bots link directly to scanners, CI pipelines, and incident‑response scripts, turning chat into a command console. Core elements include: Immediate notification – Findings appear in a channel the moment scanners detect them, tagged with severity and suggested fixes. Command shortcuts – A simple slash command can restart a build, add a JIRA ticket, or roll back a com…  ( 4 min )

Insurance Core Insurance Platform: Definition A core insurance platform serves as the digital backbone of an insurer, integrating essential functions like policy management, underwriting, billing, claims, and often CRM into a single system. This unified approach improves data accuracy, automates manual tasks, embeds compliance into workflows, and helps reduce costs and risks. Modern core platforms are typically cloud-native and API-first, offering scalability, seamless upgrades, and easy integration with tools like generative AI, embedded insurance forms, and real-time pricing engines. According to McKinsey, cloud-enabled core systems are now key to faster product launches, real-time insights, and broader ecosystem connectivity—making modernization a strategic priority for 2025.

Look, whether you’re a Linux user, a hardcore webdev, or even an IT technician, docs are a part of all of tech, but few people actually understand how to read them and more specifically absorb them. If you prefer to consume this article as a video, check this out! Now look, I hear you saying “but Oscar, I just read the whole Rust book” or “I just read what I can’t figure out on my own – people don’t know how to read documentation because these 20 page documents aren't necessary anymore”, and we’ll get to that in a second. Because yes, you’re right, documentation comes in many forms – READMEs, autodocs, and even videos (yes, Google makes videos sometimes instead of writing documentation). And as we get better at documenting our stuff, the need to have the patience to read through that 20 …  ( 9 min )
